ASP.NET Core 2.1 Release: What To Expect in 2018

ASP.NET Core 2.1 Release: What To Expect in 2018

ASP NET Core 2.0 was made openly accessible on August 14. Other than ASP NET Core, .NET Standard 2.0 was discharged, the standard to which ASP.NET Core 2.0 consents, and additionally Entity Framework Core 2.0 and ASP.NET Core 2.0. Really cool, all have a similar form number, yet I’m certain this won’t go on until the end of time! I nearly disregarded NuGet, which additionally got a form knock,…

Future Scope & Demand of .NET MVC Technology

There is a tremendous demand for.NET developers because the majority of Indian corporations utilise the.NET framework to create software for their companies.

However, I think and feel that NET is gaining popularity for full-stack development and mobile apps. The demand for C# and Net will not decrease. Backend services are necessary for the majority of what we perform in an application.

It appears that NET is expanding daily. It goes without saying that specialising in the Dot Net stream will make you a versatile, talented, and in-demand programmer.

India is becoming a rapidly developing nation in terms of online development. Professional developers of ASP.NET | Open-source web framework for.NET will be in greater demand, and the future of ASP.NET | Open-source web framework for.NET in India is promising. More than half of all websites on the internet are now developed using active server page tools, illustrating the success of ASP.NET | Open-source web framework for.NET.

Other Considerations

The new language features in C# 8.0 include Async Stream, Ranges, Nullable Reference Types, and Pattern Matching, to name just a few. They won't, however, be accessible on the legacy.NET Framework or.NET Core 2.2, 2.1, or 1.0; they will only be accessible on.NET Core 3.0 and higher. It appears clear that.NET is obsolete and that.NET Core is the future.

You must review your project's APIs to determine which ones are compatible with.NET Core and which ones are not if you wish to port.NET applications to this framework. A tool for analysing and figuring out how adaptable your application is across.NET platforms is the.NET Portability Analyzer.

Conclusion:

As a.NET developer, you ought to anticipate where the platform will go in the future. It is useless because Blazor will take care of learning JavaScript for SPA frameworks. Python is no longer necessary for machine learning because ML.NET will take care of it. One no longer has to learn Swift or Android thanks to Xamarin. If you are familiar with C#, you can now build apps that work on everything from IoT to the cloud. However, this change would have an impact on a large number of enterprise clients who use frameworks and solutions based on WCF and Web Forms.

In this article, you'll learn how to install .NET Core on macOS. .NET Core is made up of the runtime and the SDK. The runtime is used to run a .NET Core app and may or may not be included with the app. The SDK is used to create .NET Core apps and libraries. The .NET Core runtime is always installed with the SDK.

The latest version of .NET Core is 3.1.

Supported releases

The following table is a list of currently supported .NET Core releases and the versions of macOS they're supported on. These versions remain supported either the version of .NET Core reaches end-of-support.

A ✔️ indicates that the version of .NET Core is still supported.

A ❌ indicates that the version of .NET Core isn't supported.

Operating System.NET Core 2.1.NET Core 3.1.NET 5 PreviewmacOS 10.15 'Catalina'✔️ 2.1 (Release notes)✔️ 3.1 (Release notes)✔️ 5.0 Preview (Release notes)macOS 10.14 'Mojave'✔️ 2.1 (Release notes)✔️ 3.1 (Release notes)✔️ 5.0 Preview (Release notes)macOS 10.13 'High Sierra'✔️ 2.1 (Release notes)✔️ 3.1 (Release notes)✔️ 5.0 Preview (Release notes)macOS 10.12 'Sierra'✔️ 2.1 (Release notes)❌ 3.1 (Release notes)❌ 5.0 Preview (Release notes)

Unsupported releases

The following versions of .NET Core are ❌ no longer supported. The downloads for these still remain published:

3.0 (Release notes)

2.2 (Release notes)

2.0 (Release notes)

Runtime information

The runtime is used to run apps created with .NET Core. When an app author publishes an app, they can include the runtime with their app. If they don't include the runtime, it's up to the user to install the runtime.

There are three different runtimes you can install on macOS:

ASP.NET Core runtime Microsoft expression media for mac. Runs ASP.NET Core apps. Includes the .NET Core runtime.

.NET Core runtime This runtime is the simplest runtime and doesn't include any other runtime. It's highly recommended that you install ASP.NET Core runtime for the best compatibility with .NET Core apps.

SDK information

The SDK is used to build and publish .NET Core apps and libraries. Installing the SDK includes both runtimes: ASP.NET Core and .NET Core.

Dependencies

.NET Core is supported on the following macOS releases:

.NET Core VersionmacOSArchitectures3.1High Sierra (10.13+)x64More information3.0High Sierra (10.13+)x64More information2.2Sierra (10.12+)x64More information2.1Sierra (10.12+)x64More information

Beginning with macOS Catalina (version 10.15), all software built after June 1, 2019 that is distributed with Developer ID, must be notarized. This requirement applies to the .NET Core runtime, .NET Core SDK, and software created with .NET Core.

The installers for .NET Core (both runtime and SDK) versions 3.1, 3.0, and 2.1, have been notarized since February 18, 2020. Prior released versions aren't notarized. If you run a non-notarized app, you'll see an error similar to the following image:

For more information about how enforced-notarization affects .NET Core (and your .NET Core apps), see Working with macOS Catalina Notarization.

libgdiplus

.NET Core applications that use the System.Drawing.Common assembly require libgdiplus to be installed.

An easy way to obtain libgdiplus is by using the Homebrew ('brew') package manager for macOS. After installing brew, install libgdiplus by executing the following commands at a Terminal (command) prompt:

Install with an installer

Android Sdk Download Mac

macOS has standalone installers that can be used to install the .NET Core 3.1 SDK:

Download and manually install

As an alternative to the macOS installers for .NET Core, you can download and manually install the SDK and runtime. Manual install is usually performed as part of continuous integration testing. For a developer or user, it's generally better to use an installer.

If you install .NET Core SDK, you don't need to install the corresponding runtime. First, download a binary release for either the SDK or the runtime from one of the following sites:

Quick tip about Basilisk II if you do not have a real old Mac: it even reads high density Mac floppy disks using a normal PC floppy drive! I salvaged many old files using it while 5 different Windows apps failed at the task. I highly recommend backing up all your floppy disks using Basilisk II before it's too late!

OldVersion.com provides free. software downloads for old versions of programs, drivers and games. So why not downgrade to the version you love? Because newer is not always bett.

✔️ .NET 5.0 preview downloads

✔️ .NET Core 3.1 downloads

✔️ .NET Core 2.1 downloads

Next, extract the downloaded file and use the export command to set variables used by .NET Core and then ensure .NET Core is in PATH.

To extract the runtime and make the .NET Core CLI commands available at the terminal, first download a .NET Core binary release. Then, open a terminal and run the following commands from the directory where the file was saved. The archive file name may be different depending on what you downloaded.

Use the following command to extract the runtime:

Use the following command to extract the SDK:

Tip

The preceding export commands only make the .NET Core CLI commands available for the terminal session in which it was run.

You can edit your shell profile to permanently add the commands. There are a number of different shells available for Linux and each has a different profile. For example:

Bash Shell: ~/.bash_profile, ~/.bashrc

Korn Shell: ~/.kshrc or .profile

Z Shell: ~/.zshrc or .zprofile

Edit the appropriate source file for your shell and add :$HOME/dotnet to the end of the existing PATH statement. If no PATH statement is included, add a new line with export PATH=$PATH:$HOME/dotnet.

Also, add export DOTNET_ROOT=$HOME/dotnet to the end of the file.

This approach lets you install different versions into separate locations and choose explicitly which one to use by which application.

Install with Visual Studio for Mac

Visual Studio for Mac installs the .NET Core SDK when the .NET Core workload is selected. To get started with .NET Core development on macOS, see Install Visual Studio 2019 for Mac. For the latest release, .NET Core 3.1, you must use the Visual Studio for Mac 8.4.

Install alongside Visual Studio Code

Visual Studio Code is a powerful and lightweight source code editor that runs on your desktop. Visual Studio Code is available for Windows, macOS, and Linux.

While Visual Studio Code doesn't come with an automated .NET Core installer like Visual Studio does, adding .NET Core support is simple.

Download and install Visual Studio Code.

Download and install the .NET Core SDK.

Install the C# extension from the Visual Studio Code marketplace.

Install with bash automation

The dotnet-install scripts are used for automation and non-admin installs of the runtime. You can download the script from the dotnet-install script reference page.

The script defaults to installing the latest long term support (LTS) version, which is .NET Core 3.1. You can choose a specific release by specifying the current switch. Include the runtime switch to install a runtime. Otherwise, the script installs the SDK.

Android Sdk Download Zip

Note

The command above installs the ASP.NET Core runtime for maximum compatability. The ASP.NET Core runtime also includes the standard .NET Core runtime.

Android Sdk For Mac

Docker

Containers provide a lightweight way to isolate your application from the rest of the host system. Containers on the same machine share just the kernel and use resources given to your application.

.NET Core can run in a Docker container. Official .NET Core Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the Microsoft .NET Core Docker Hub repository. Each repository contains images for different combinations of the .NET (SDK or Runtime) and OS that you can use.

Microsoft provides images that are tailored for specific scenarios. For example, the ASP.NET Core repository provides images that are built for running ASP.NET Core apps in production.

How to install Visual Studio Code on a Raspberry Pi 4 in minutes

Four years ago I wrote how to BUILD (literally compile) Visual Studio Code for a Raspberry Pi ARM machine. Just a few months later in November, community member Jay Rodgers released his labor of love - nightly builds of VS Code for Chromebooks and Raspberry Pi.

If you want to get unofficial builds of Visual Studio Code running on a Raspberry Pi (I know you have one!) you should use his instructions. He has done a lot of work to make this very simple. Head over to http://code.headmelted.com/ and make it happen for yourself, now!

Jay says:

I've maintained the project for a few years now and it has expanded from providing binaries for Pi to providing support and tools to get VS Code running on low-end ARM devices that might not otherwise support it like Chromebooks (which make up about 60% of the devices in schools now).

The project has really taken off among educators (beyond what I would have thought), not least because they're restricted to the devices provided and it gives them a route to teach coding to students on these computers that might not otherwise be there.

Again, Jay is doing this out of love for the community and the work that makes it happen is hosted at https://github.com/headmelted/codebuilds. I'd encourage you to head over there right now and give him a STAR.

There's so many community members out there doing "thankless" work. Thank them. Thank them with a thank you email, a donation, or just your kindness when you file an issue and complain about all the free work they do for you.

I just picked up a Raspberry Pi 4 from Amazon, and I was able to get a community build of VS Code running on it easily!

Open a terminal, run "sudo -s" and then this script (again, the script is open source):

. <( wget -O - https://code.headmelted.com/installers/apt.sh )

Jay has done the work! That's just the apt instructions, but he's got Chrome OS, APT, YUM, and a manual option over at http://code.headmelted.com/!

Thank you for making this so much easier for us all.

İlk olarak bir MyExceptionFilter şeklinde bir class oluşturuyorum. public class MyExceptionFilter { } Şimdi class'ımı IExceptionFilter 'a kalıtacağım.   public class MyActionFilter : IExceptionFilter { } Daha sonra Override ediyoruz ve elimize  OnException metodu geliyor public class MyActionFilter : IExceptionFilter { public void OnException(ExceptionContext context) { } } context adı ile gelen parametre ile action adı controller adı gibi bilgilere erişebilirsiniz. public class MyActionFilter : IExceptionFilter { public void OnException(ExceptionContext context) { var actionName = context.RouteData.Values; var controllerName = context.RouteData.Values; } } Şimdi bu şekilde Controller ve Action'a ulaşabildik daha ne yapabiliriz derseniz burada action türüne göre sayfayı değiştirip örnek veriyorum Post ise redirect action verip hata sayfasına yönlendirebilirsiniz veya  sayfalar js ile yönetiliyorsa json döndürüp sayfa içerisinde hataları okuyup hata mesajı verebilirsiniz.   public class MyActionFilter : IExceptionFilter { public void OnException(ExceptionContext context) { var actionName = context.RouteData.Values; var controllerName = context.RouteData.Values; context.ExceptionHandled = true; context.Result = new ViewResult { ViewName = "CustomError" }; } }   Ben bir tane hata sayfasını açan bir örnek yapacağım result olarak viewresult yazıyorum içerisine viewname veriyorum. View'a nasıl erişeceğim nerede olacak diyorsanızda view dosyasındaki shared içerisine dosyayı açıp adını viewname'e verirseniz çalışacaktır. HttpStatusCode status = HttpStatusCode.InternalServerError; Şimdi ise ben status koduna bakayım sunucu hatası ise bu değilse vs buna yönlendireyim diyorsanız da  bu şekilde status koduna ulaşıp 500 ise farklı 400 ise farklı vs sayfalara gönderebilirsiniz. , Ben bunları database'e kaydetmek istiyorum ama nasıl bir tablo oluşturmalıyım diyorsanız da sizin işinizi görecek bir model atayım codefirst kullanıyor iseniz sizin ciddi anlamda işinizi çözecektir. public partial class ErrorEntity { public int ErrorEntityId { get; set; } public int? AppUserId { get; set; } public string MessageText { get; set; } public string InnerExceptionText { get; set; } public string SourceText { get; set; } public string StackTraceText { get; set; } public string ControllerName { get; set; } public string ActionName { get; set; } public string ParameterName { get; set; } public int? StatusCode { get; set; } public string Status { get; set; } public string UserBrowser { get; set; } public string UserIp { get; set; } public string ApiController { get; set; } public string ApiAction { get; set; } public string WebController { get; set; } public string WebAction { get; set; } public DateTime CreateDate { get; set; } public bool? IsActive { get; set; } public bool? IsDeleted { get; set; } public AppUser AppUser { get; set; } }       Yazıyı burada bitireyim muhtemelen bir sonraki konu action filter ile loglama şeklinde olabilir ancak ana fikir zaten neredeyse aynı. Sürüm olarak 2.1 ve 3.1 de kodlar çalışmaktadır.   Read the full article

How to edit user information in asp.net core vs 2.1?

How to edit user information in asp.net core vs 2.1?

(adsbygoogle = window.adsbygoogle || []).push();

Article : https://sagarjaybhay.com/how-to-register-new-user-using-asp-net-core-identity/

Edit User Information In Asp.Net Core

For every edit operation or update operation, it is good practice to create a view model for that information class. As we are editing users class we can create here EditUserViewModel Class and added some properties which are shown below.

(adsbygoogle = window.adsbygoogle || []).push();

public class EditUserViewModel public string Id get; set; [Required] public string UserName get; set; [Required] [EmailAddress] public string Email get; set; public string City get; set; public List<string> Claims get; set; =new List<string>(); public List<string> Roles get; set; =new List<string>();

For edit user we create one method which is EditUser action method in our RoleManagController and In this method we pass User Id from edit button click event from our list of users view.

By using this Id we can find user by using UserManager service which is injected in our controller. The code of this method shown below.

[HttpGet] public async Task<IActionResult> EditUser(string Id) var user = await _userManager.FindByIdAsync(Id); if (user == null) ViewBag.ErrorMessage = $"UserID :Id of this customer is not found."; return View("NotFound"); var userClaims = await _userManager.GetClaimsAsync(user); var userRoles = await _userManager.GetRolesAsync(user); var model=new EditUserViewModel() Id = Id, City = user.City, UserName = user.UserName, Email = user.Email, Claims = userClaims.Select(c=>c.Value).ToList(), Roles = userRoles.ToList() ; return View(model);

In this, we first check the user is valid or present or not. If the user presents then by using a usermanager service object we can get access to the claims which are in-built methods provided in asp.net core similarly we can get roles from Users by using the in-built method GetRolesAsync method and we can set the properties of our EditUserViewModel class.

Then we pass this Viewmodel class object to our view and we show edit user information form. For this view, we can use an in-built edit form property to create a view.

Edit view Code is below

@model LearnAspCore.ViewModel.EditUserViewModel @ ViewData["Title"] = "EditUser"; <h1>EditUser</h1> <hr /> <div class="row"> <div class="col-md-4"> <form asp-action="EditUser"> <div asp-validation-summary="ModelOnly" class="text-danger"></div> <div class="form-group"> <label asp-for="Id" class="control-label"></label> <input asp-for="Id" class="form-control" disabled="disabled" /> <span asp-validation-for="Id" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="UserName" class="control-label"></label> <input asp-for="UserName" class="form-control" /> <span asp-validation-for="UserName" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="Email" class="control-label"></label> <input asp-for="Email" class="form-control" /> <span asp-validation-for="Email" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="City" class="control-label"></label> <input asp-for="City" class="form-control" /> <span asp-validation-for="City" class="text-danger"></span> </div> <div class="form-group"> <input type="submit" value="Save" class="btn btn-primary" /> </div> </form> </div> </div> <hr /> <hr /> <div class="card"> <div class="card-header"> <h2>User Roles</h2> </div> <div class="card-body"> @if (Model.Roles.Any()) foreach (var role in Model.Roles) <h3 class="card-title">@role</h3> else <h1 class="text-danger">No Roles Present Currently For this User.</h1> </div> <div class="card-footer"> <a href="#" class="btn btn-primary">Manage Roles</a> </div> </div> <hr /> <hr /> <div class="card"> <div class="card-header"> <h2>User Claims</h2> </div> <div class="card-body"> @if (Model.Claims.Any()) foreach (var claim in Model.Claims) <h3 class="card-title">@claim</h3> else <h1 class="text-danger">No Claim Present Currently For this User.</h1> </div> <div class="card-footer"> <a href="#" class="btn btn-primary">Manage Claims</a> </div> </div> <div> <a asp-action="Index" asp-controller="Home">Back to List</a> </div>

Edit User In Asp.Net Core

Now we want to store this edited information into our database for that we create another method with the same name EditUser but the attribute of that method is HttpPost why? Because we created the in our edit view we use to form and the action method of this form is EditUser.

Edit User Post Action in Asp.Net Core

The code for update user information to the database is below

[HttpPost] public async Task<IActionResult> EditUser(EditUserViewModel userView) var user = await _userManager.FindByIdAsync(userView.Id); if (user == null) ViewBag.ErrorMessage = $"UserID :userView.Id of this customer is not found."; return View("NotFound"); else user.Email = userView.Email; user.City = userView.City; user.Email = userView.Email; var result = await _userManager.UpdateAsync(user); if (result.Succeeded) return RedirectToAction("ListOfUsers"); foreach (var error in result.Errors) ModelState.AddModelError("",error.Description); return View(userView);

In the above code first, we check whether the user is valid or not. If he is a valid user then we assign our EditUserViewModel properties to our existing user which is updated properties and after that, we use the UpdateAsync method of UserManager class and this is in-built service and we are injected in our controller.

After update button click if information is updated successfully we redirect the user to List of Users page. Complete code of controller is below.

using System; using System.Collections.Generic; using System.Linq; using LearnAspCore.ViewModel; using Microsoft.AspNetCore.Identity; using Microsoft.AspNetCore.Mvc; using System.Threading.Tasks; using LearnAspCore.Models; using Microsoft.AspNetCore.Authorization; using Microsoft.AspNetCore.Identity.UI.V3.Pages.Internal.Account; namespace LearnAspCore.Controllers [Authorize(Roles = "Admin")] public class RolemanagController : Controller private readonly UserManager<ExtendedIdentityUser> _userManager; public RoleManager<IdentityRole> rolesManager get; set; public RolemanagController(RoleManager<IdentityRole> rolesManager,UserManager<ExtendedIdentityUser> userManager) _userManager = userManager; this.rolesManager = rolesManager; [HttpGet] public IActionResult CreateRoles() return View(); [HttpPost] public async Task<IActionResult> CreateRoles(RoleViewModel roleView) if (ModelState.IsValid) IdentityRole role=new IdentityRole() Name = roleView.RoleName ;

.NET Core 3.0 穩定版發布

訪問:

微軟中國官方商城 – 首頁

.NET Conf 2019 直播地址：https://www.dotnetconf.net/

作為一個大版本更新，.NET Core 3.0 引入了大量改進和新特性，例如新增加的 Windows Forms 和 WPF、新的 JSON API、對 ARM64 架構的支持，以及全面提升的性能。對了，C# 8 也是 .NET Core 3.0 本次更新的一部分，其中包括可空引用類型（nullable）、異步流（Async Streams）和更多的模式。

除了 C# 8，.NET Core 3.0 的更新內容還包括 F# 4.7，此版本主要是對語法進行改進，並將目標平台升級至面向 .NET Standard 2.0。

.NET 團隊表示 .NET Core 3.0 會兼容之前的版本，所以大家現在就可以將項目升級至 .NET Core 3.0。

.NET Core 3.0 的一些“新料”

在深入探究 .NET Core 3.0 的所有新功能之前，先來看看一些重要的改進，其中提及到了 C# 8、F# 4.7、.NET Standard 2.1、在其他發行版上的支持情況等。

在 .NET Core 3.0 穩定版發布前，它已在 dot.net 和 Bing.com 這兩個網站上運行了數月，並已通過嚴格的測試。微軟的團隊也將很快在生產環境中將工作負載部署到 .NET Core 3.0 上。

許多組件的性能都獲得了巨大提升，詳情可查看介紹 .NET Core 3.0 性能改進的內容。

C# 8 增加了異步流(async streams)、範圍類型和索引類型(range/index）、更多的模式以及可空引用類型。可空引用類型主要��於幫助我們處理無處不在的空引用異常(NullReferenceException)，另外，框架庫的底層已被註釋，編譯器會分析代碼流，因此我們能查看null值是否可以將其用於當前位置。

F# 4.7 主要是通過使用隱式的yield表達式來簡化一些操作，以及語法。此外還提供了對LangVersion的支持、新增nameof關鍵字，和處於預覽階段的靜態類。 F# 核心庫的目標平台為 .NET Standard 2.0，詳情點此了解。

.NET Standard 2.1增加了可以在代碼中使用的類型集，它們也可同時用於 .NET Core 和 Xamarin。

.NET Core 現在已為 Windows 桌面應用提供支持、同時支持 Windows Forms 和 WPF（已開源）。 WPF 設計器已屬於 Visual Studio 2019 16.3 的一部分。 Windows Forms 設計器則仍處於預覽階段，可從 VSIX 進行下載。

.NET Core 應用現在默認情況下就具有可執行文件。在之前的版本中，需要通過dotnet命令來啟動應用，如dotnet myapp.dll。不過從這個版本開始，我們可以使用特定於應用程序的可執行文件（例如 myapp或./myapp, ）來啟動應用程序，具體取決於操作系統。

新增高性能的 JSON API，用於讀取器/寫入器、對像模型和序列化方案。這些 API 基於Span從頭開始構建，使用 UTF8 來替代 UTF16（如 string），另外由於這些 API 使用了最小化的內存分配，因此帶來了更好的性能，減少了垃圾回收器的工作。詳情請查看 The future of JSON in .NET Core 3.0。

默認情況下，垃圾回收器使用更少的內存。對於許多應用程序託管在同一服務器上的情況，此改進非常有用。此外，新版本中 GC 能更好地利用具有 64 核（或大於）的機器的核心數量。

.NET Core 強化了對 Docker 的支持，以使 .NET 應用程序在容器中能按預期且有效地運行。當容器被配置為有限的內存或 CPU 時，垃圾回收器和線程池會更好地進行適���已提供最具優化效果的運行方式。 .NET Core 的 Docker 鏡像體積也更小 —— 尤其是 SDK 鏡像。

支持 Raspberry Pi 和 ARM 芯片，以助力 IoT 開發。其中包括遠程 Visual Studio 調試器。這就意味著我們可以使用新的 GPIO API 來部署可監聽傳感器的應用程序，並在顯示器上打印消息或圖像。 ASP.NET 可用於將數據暴露為 API，或作為一個在 IoT 設備啟用配置的站點。

.NET Core 3.0 會被 11 月發布的 .NET Core 3.1 取代，因為後者才是LTS 版本（至少會獲得三年的技術支持），不過官方還是建議大家先升級到 .NET Core 3.0，然後再升級到 3.1，這樣過渡起來更方便。

.NET Core 2.2 將於今年 12.23 到達 EOL 階段。查看 .NET Core support policy。

.經過與 Red Hat 的多年合作，.NET Core 3.0 將隨 RHEL 8 在 Red Hat Application Streams 中一起提供。

Visual Studio 用戶如需在 Windows 上使用 .NET Core 3.0，需要升級至 Visual Studio 2019 16.3。

Visual Studio 用戶如需在 macOS 上使用 .NET Core 3.0，需要升級至 Visual Studio for Mac 8.3。

Visual Studio Code 用戶則需要使用最新版本的 C# 擴展，以確保最新的方案能夠正常工作，包括針對 .NET Core 3.0 的目標平台。

.NET Core 3.0 的 Azure App Service 部署目前正在進行中。

.NET Core 3.0 的 Azure Dev Ops 部署即將推出。

.NET Core 3.0 支持的平台

Alpine: 3.9+

Debian: 9+

openSUSE: 42.3+

Fedora: 26+

Ubuntu: 16.04+

RHEL: 6+

SLES: 12+

macOS: 10.13+

Windows Client: 7, 8.1, 10 (1607+)

Windows Server: 2012 R2 SP1+

要注意的是，Windows Forms 和 WPF 應用僅支持在 Windows 上運行。

對芯片的支持情況如下：

x64 on Windows, macOS, and Linux

x86 on Windows

ARM32 on Windows and Linux

ARM64 on Linux (kernel 4.14+)

注意：請確保 .NET Core 3.0 在 ARM64 上的部署使用 Linux Kernel 4.14 或更高版本。例如，Ubuntu 18.04 能滿足此要求，但 16.04 卻不滿足。

Getting Started with .NET Core and Docker and the Microsoft Container Registry

It's super easy to get started with .NET Core and/or ASP.NET Core with Docker. If you have Docker installed you don't need to install anything to try out .NET Core, of course.

To run a little .NET Core console app:

docker run --rm mcr.microsoft.com/dotnet/core/samples:dotnetapp

And the result:

latest: Pulling from dotnet/core/samples Hello from .NET Core! ...SNIP... **Environment** Platform: .NET Core OS: Linux 4.9.125-linuxkit #1 SMP Fri Sep 7 08:20:28 UTC 2018

To run a quick little ASP.NET Core website just:

docker run -it --rm -p 8000:80 --name aspnetcore_sample mcr.microsoft.com/dotnet/core/samples:aspnetapp

And here it is running on localhost:8000

You can also host ASP.NET Core Images with Docker over HTTPS to with this image, or run ASP.NET Core apps in Windows Containers.

Note that Microsoft teams are now publishing container images to the MCR (Microsoft Container Registry) so they can use the Azure CDN and pull faster when they are closer to you globally. The images start at MCR and then can be syndicated to other container registries.

The new repos follow:

.NET Core Runtime dependencies (just the stuff .NET Core needs, but not .NET Core itself - useful if you want to distribute your own copy and still want a small container image size)

.NET Core Runtime (Just what's needed to run a .NET Core app)

.NET Core SDK (includes the compilers, everything)

ASP.NET Core runtime (everything you need to RUN your ASP.NET Core web app)

When you "docker pull" you can use tag strings for .NET Core and it works across any supported .NET Core version

SDK: docker pull mcr.microsoft.com/dotnet/core/sdk:2.1

ASP.NET Core Runtime: docker pull mcr.microsoft.com/dotnet/core/aspnet:2.1

.NET Core Runtime: docker pull mcr.microsoft.com/dotnet/core/runtime:2.1

.NET Core Runtime Dependencies: docker pull mcr.microsoft.com/dotnet/core/runtime-deps:2.1

For example, I can run the .NET Core 3.0 SDK and mess around with it like this:

docker run -it mcr.microsoft.com/dotnet/core/sdk:3.0

I've been using Docker to run my unit tests on my podcast site within a container locally. Then I volume mount and dump the test results out in a local folder and inspect them with Visual Studio

docker build --pull --target testrunner -t podcast:test . docker run --rm -v c:\github\hanselminutes-core\TestResults:/app/hanselminutes.core.tests/TestResults podcast:test

I can then either host the Docker container in Azure App Service for Containers, or as little one-off per-second billed instances with Azure Container Instances (ACI).

Have you been using .NET Core in Docker? How has it been going for you?

Customizing Automatic HTTP 400 Error Response in ASP.NET Core Web APIs

Annotating the controllers with ApiController attribute in ASP.NET Core 2.1 or higher will enable the behavioral options for the API's. These behavioral options include automatic HTTP 400 responses as well. In this post, we'll see how we can customize the default error response from the ASP.NET Core Web API. Default Error Response If you are creating a new default ASP.NET Core web API project, then you'd see the ValuesController.cs file in the project. Otherwise, create a Controller and create an action method to a parameter to test the automatic HTTP 400 responses. http://bit.ly/2ObXV2P
