Dot net developers and dot net companies must be well versed with its key offerings, USPs, as well as crucial aspects of the framework and its functioning. This post provides you with all-inclusive information about the dot net development ecosystem.  Here we commence!

Dot net Framework:  A Synopsis

Dot Net (.Net) is a free, open-source, cross-platform software development platform devised by Microsoft. It is used for architecting various kinds of apps for mobile, web, desktop, gaming, and IoT platforms. It is also used for building websites and web services. With the dot net framework, one can use various languages, libraries, and editors.

The first version - .Net framework 1.0 – was launched in 2002 and was meant to develop apps for the Windows platforms. Thereafter, Microsoft has rolled out several enhanced versions to keep this framework updated with changing market trends; the latest version being .Net framework 6.12.0.122.

Using dot net, you can build Web-based as well as Form-based Apps applications. This framework is known for supporting a wide range of programming languages including Visual Basic, C#, and F#; and this provides plenty of choice to the .Net app developers while crafting app solutions.

Dot net: Key Offerings

A Huge Collection of Comprehensive Libraries

The Dot Net eco-system offers a huge assemblage of pre-defined libraries offering simple/complex data structures. It is a systematic app development ecosystem that ensures quality and also enables reengineering and migration. Moreover, .Net extends its support to a plethora of languages, technologies, and software tools. Consequently, dot net developers enjoy the privilege of creating functionalities that are based on the needs and accordingly write the code. Furthermore, a dedicated library for functions like encryption, database access, security, etc. is also available.

ASP.NET: Back-end Development Tool

ASP.NET, a crucial and handy software tool, is an open-source web app creation platform for executing back-end functions. It is the key tool offered by the Dot Net eco-system for developing various dynamic web solutions like websites, web apps, web services, etc. with JavaScript, CSS, HTML, and server scripting. Any .Net language can be used for writing ASP.NET apps.

The presence of the ASP .NET MVC (Model-View-Controller) architecture is another USP of the dot net framework. On account of this development model, there’s better separation between the app’s code and the UI code and it becomes easier for software professionals to perform unit tests as well as to conduct Test-driven Development (TDD). This leads to better code management and guarantees code security. Owing to the MVC approach, .Net developers need not worry about ViewState and IsPostBack each time and hence can build apps as per their natural workflow, resulting in improved efficiency.

Moreover, ASP .Net WebHooks are used to connect Web APIs with SaaS services. It also allows using additional extensions that facilitate web development.

Visual Basic .Net and C#: Main Programming Languages

The Dot Net framework consists of as many as thirty-two programming languages including Visual Basic .Net, C#, F#, Boo, A Sharp, Cobra, Oxygene, IronPython, Fantom, etc. Out of these, Visual Basic .Net and C# are the most notable ones. Both of these languages are used for the front-end development of various kinds of apps starting from web solutions to desktop apps.

C# is an object-oriented language and is quite similar to Java and C++. It has been designed to meet the needs of the Dot Net platform and facilitates in crafting complex app solutions that are scalable and flexible as well.

Visual Basic .Net is also an object-oriented language meant for the .Net platform. It is employed for creating large-scale web apps, gaming apps, simple command-line tools, and graphical user interfaces.

Visual Studio

Visual Studio is a powerful IDE (Integrated Development Environment) used for writing the .Net and C# programs and is free to download. It supports an array of functions like interface designing, code editing, debugging, server management, analyzing performances, etc.

Ability to build Different Types of Applications

This programming framework comes with a plethora of features and guidelines; and is capable of developing apps/solutions for diverse platforms including mobile, web, and Windows.

Dot net: Crucial Aspects to watch out for

Dot Net is now Open-source

The .Net framework became open-source in 2014. To be precise, certain portions of the framework are available under the open-source license. C# Roslyn is an example of an open-source compiler created by Microsoft, under the Apache license; its source code can be downloaded from GitHub.  Owing to its open-source nature, the .Net framework enjoys the following advantages:

It can be used as well as distributed amongst users for free

Users can mold this framework to suit their project requirements

The open-source environment enables direct project access to the project vendors, partners as well as associates. Project vendors can download and make changes to the project; whereas vendor partners can only download the project.

Dot Net is not meant for Windows Only

Initially, .Net was meant for Windows only. But, after the NET Core update rolled out by Microsoft in 2016, Dot Net can now run on several platforms such as Mac OS X and Linux. On account of being an open-source as well as a cross-platform development technology, it enables developers to add new platforms to applications. It is also employed for building Cloud and IoT apps and offers several libraries, a compiler, and a core runtime.

Support for Single-File Apps

The updated version .NET 5 had added the support for single-file apps. This feature allows the .NET developers to publish/deploy apps and their dependencies as a single file; wherein the dependencies are bundled into one file. In earlier versions, single-file apps could support binaries only. But .NET 5 update provides a new internal structure that supports direct execution and at the same time, doesn’t affect performance.

A Unified System with CLR and FCL

The dot net framework consists of the CLR and FCL. The function of CLR or the Common Language Runtime is to manage the program execution written in various languages; while FCL or the Framework Class Library is a set of standardized types that helps in running .net apps. CLR and FCL together create an eco-system that enables different programming languages to interact natively, thereby representing a unified system.

A Big Umbrella: .Net’s Compatibility and Interoperability

Dot Net is considered to be a big umbrella as it is compatible with a plethora of tools, technologies as well as languages. It offers a systematic eco-system for software development that is not only a good choice for app building, app migration, and reengineering; but also comes with a promise of quality assurance.

Besides its support for a wide range of tools, skillsets, and languages; this framework offers interoperability as well. Interoperability refers to the capability of specific software or hardware to virtually work with various kinds of hardware/software, including the ones that have not yet been discovered. Dot Net is interoperable with most standard programming languages and operating eco-systems.

Its interoperability can be classified into three broad categories – COM interop (dot net with COM components); P/Invoke (dot net with Win32 DLLs); and .Net interop (COM components with dot net). COM refers to the Component Object Model that was introduced by Microsoft as the binary-interface standard in between 2 binary modules – a user-run program and a library. COM explains the standard through which these two binary modules unite as well as interact with each other. Accessing the .Net components from COM components using dot net runtime is referred to as forwarding compatibility, whereas, accessing the old code COM from dot net components is known as backward compatibility.

Adopted by Several Big Players

The Dot Net technology has been adopted by several top-layer global companies across diverse industrial domains. Some of them are Accenture, Dell, TCS, Epic Systems, Dell, Quicken Loans, and TitleSource. These big market players trust the .Net framework owing to its reliability, easy learning curve, and popularity amongst developers.

Final Thoughts

Thus, .Net is a standard software framework that programs and runs mobile as well as web apps seamlessly. Its integrated development environment ushers in myriad advantages for developing software solutions. And, the good news is that the .Net core framework awaits a brighter future ahead and is expected to grow exponentially in the years to come.

Building, Running, and Testing .NET Core and ASP.NET Core 2.1 in Docker on a Raspberry Pi (ARM32)

I love me some Raspberry Pi. They are great little learning machines and are super fun for kids to play with. Even if those kids are adults and they build a 6 node Kubernetes Raspberry Pi Cluster.

Open source .NET Core runs basically everywhere - Windows, Mac, and a dozen Linuxes. However, there is an SDK (that compiles and builds) and a Runtime (that does the actual running of your app). In the past, the .NET Core SDK (to be clear, the ability to "dotnet build") wasn't supported on ARMv7/ARMv8 chips like the Raspberry Pi. Now it is.

.NET Core is now supported on Linux ARM32 distros, like Raspbian and Ubuntu!

Note: .NET Core 2.1 is supported on Raspberry Pi 2+. It isn’t supported on the Pi Zero or other devices that use an ARMv6 chip. .NET Core requires ARMv7 or ARMv8 chips, like the ARM Cortex-A53. Folks on the Azure IoT Edge team use the .NET Core Bionic ARM32 Docker images to support developers writing C# with Edge devices.

There's two ways to run .NET Core on a Raspberry Pi.

One, use Docker. This is literally the fastest and easiest way to get .NET Core up and running on a Pi. It sounds crazy but Raspberry Pis are brilliant little Docker container capable systems. You can do it in minutes, truly. You can install Docker quickly on a Raspberry Pi with just:

curl -sSL https://get.docker.com | sh sudo usermod -aG docker pi

After installing Docker you'll want to log in and out. You might want to try a quick sample to make sure .NET Core runs! You can explore the available Docker tags at https://hub.docker.com/r/microsoft/dotnet/tags/ and you can read about the .NET Core Docker samples here https://github.com/dotnet/dotnet-docker/tree/master/samples/dotnetapp

Now I can just docker run and then pass in "dotnet --info" to find out about dotnet on my Pi.

pi@raspberrypi:~ $ docker run --rm -it microsoft/dotnet:2.1-sdk dotnet --info .NET Core SDK (reflecting any global.json): Version: 2.1.300-rc1-008673 Commit: f5e3ddbe73 Runtime Environment: OS Name: debian OS Version: 9 OS Platform: Linux RID: debian.9-x86 Base Path: /usr/share/dotnet/sdk/2.1.300-rc1-008673/ Host (useful for support): Version: 2.1.0-rc1 Commit: eb9bc92051 .NET Core SDKs installed: 2.1.300-rc1-008673 [/usr/share/dotnet/sdk] .NET Core runtimes installed: Microsoft.NETCore.App 2.1.0-rc1 [/usr/share/dotnet/shared/Microsoft.NETCore.App] To install additional .NET Core runtimes or SDKs: https://aka.ms/dotnet-download

This is super cool. There I'm on the Raspberry Pi (RPi) and I just ask for the dotnet:2.1-sdk and because they are using "multiarch" docker files, Docker does the right thing and it just works. If you want to use .NET Core on ARM32 with Docker, you can use any of the following tags.

Note: The first three tags are multi-arch and bionic is Ubuntu 18.04. The codename stretch is Debian 9. So I'm using 2.1-sdk and it's working on my RPi, but I can be specific if I'd prefer.

2.1-sdk

2.1-runtime

2.1-aspnetcore-runtime

2.1-sdk-stretch-arm32v7

2.1-runtime-stretch-slim-arm32v7

2.1-aspnetcore-runtime-stretch-slim-arm32v7

2.1-sdk-bionic-arm32v7

2.1-runtime-bionic-arm32v7

2.1-aspnetcore-runtime-bionic-arm32v7

Try one in minutes like this:

docker run --rm microsoft/dotnet-samples:dotnetapp

Here it is downloading the images...

In previous versions of .NET Core's Dockerfiles it would fail if you were running an x64 image on ARM:

standard_init_linux.go:190: exec user process caused "exec format error"

Different processors! But with multiarch per https://github.com/dotnet/announcements/issues/14 Kendra from Microsoft it just works with 2.1.

Docker has a multi-arch feature that microsoft/dotnet-nightly recently started utilizing. The plan is to port this to the official microsoft/dotnet repo shortly. The multi-arch feature allows a single tag to be used across multiple machine configurations. Without this feature each architecture/OS/platform requires a unique tag. For example, the microsoft/dotnet:1.0-runtime tag is based on Debian and microsoft/dotnet:1.0-runtime-nanoserver if based on Nano Server. With multi-arch there will be one common microsoft/dotnet:1.0-runtime tag. If you pull that tag from a Linux container environment you will get the Debian based image whereas if you pull that tag from a Windows container environment you will get the Nano Server based image. This helps provide tag uniformity across Docker environments thus eliminating confusion.

In these examples above I can:

Run a preconfigured app within a Docker image like:

docker run --rm microsoft/dotnet-samples:dotnetapp

Run dotnet commands within the SDK image like:

docker run --rm -it microsoft/dotnet:2.1-sdk dotnet --info

Run an interactive terminal within the SDK image like:

docker run --rm -it microsoft/dotnet:2.1-sdk

As a quick example, here I'll jump into a container and new up a quick console app and run it, just to prove I can. This work will be thrown away when I exit the container.

pi@raspberrypi:~ $ docker run --rm -it microsoft/dotnet:2.1-sdk root@063f3c50c88a:/# ls bin boot dev etc home lib media mnt opt proc root run sbin srv sys tmp usr var root@063f3c50c88a:/# cd ~ root@063f3c50c88a:~# mkdir mytest root@063f3c50c88a:~# cd mytest/ root@063f3c50c88a:~/mytest# dotnet new console The template "Console Application" was created successfully. Processing post-creation actions... Running 'dotnet restore' on /root/mytest/mytest.csproj... Restoring packages for /root/mytest/mytest.csproj... Installing Microsoft.NETCore.DotNetAppHost 2.1.0-rc1. Installing Microsoft.NETCore.DotNetHostResolver 2.1.0-rc1. Installing NETStandard.Library 2.0.3. Installing Microsoft.NETCore.DotNetHostPolicy 2.1.0-rc1. Installing Microsoft.NETCore.App 2.1.0-rc1. Installing Microsoft.NETCore.Platforms 2.1.0-rc1. Installing Microsoft.NETCore.Targets 2.1.0-rc1.

If you try it yourself, you'll note that "dotnet run" isn't very fast. That's because it does a restore, build, and run. Compilation isn't super quick on these tiny devices. You'll want to do as little work as possible. Rather than a "dotnet run" all the time, I'll do a "dotnet build" then a "dotnet exec" which is very fast.

If you're doing to do Docker and .NET Core, I can't stress enough how useful the resources are over at https://github.com/dotnet/dotnet-docker.

ARM32 / Raspberry Pi

.NET Core ARM32 Docker Sample - This sample builds and runs an application with Debian on ARM32 (works on Raspberry Pi).

ASP.NET Core ARM32 Docker Sample - This sample builds and runs an ASP.NET Core application with Debian on ARM32 (works on Raspberry Pi).

I found the samples to be super useful...be sure to dig into the Dockerfiles themselves as it'll give you a ton of insight into how to structure your own files. Being able to do Multistage Dockerfiles is crucial when building on a small device like a RPi. You want to do as little work as possible and let Docker cache as many layers with its internal "smarts." If you're not thoughtful about this, you'll end up wasting 10x the time building image layers every build.

Dockerizing a real ASP.NET Core Site with tests!

Can I take my podcast site and Dockerize it and build/test/run it on a Raspberry Pi? YES.

FROM microsoft/dotnet:2.1-sdk AS build WORKDIR /app # copy csproj and restore as distinct layers COPY *.sln . COPY hanselminutes.core/*.csproj ./hanselminutes.core/ COPY hanselminutes.core.tests/*.csproj ./hanselminutes.core.tests/ RUN dotnet restore # copy everything else and build app COPY . . WORKDIR /app/hanselminutes.core RUN dotnet build FROM build AS testrunner WORKDIR /app/hanselminutes.core.tests ENTRYPOINT ["dotnet", "test", "--logger:trx"] FROM build AS test WORKDIR /app/hanselminutes.core.tests RUN dotnet test FROM build AS publish WORKDIR /app/hanselminutes.core RUN dotnet publish -c Release -o out FROM microsoft/dotnet:2.1-aspnetcore-runtime AS runtime WORKDIR /app COPY --from=publish /app/hanselminutes.core/out ./ ENTRYPOINT ["dotnet", "hanselminutes.core.dll"]

Love it. Now I can "docker build ." on my Raspberry Pi. It will restore, test, and build. If the tests fail, the Docker build will fail.

See how there's an extra section up there called "testrunner" and then after it is "test?" That testrunner section is a no-op. It sets an ENTRYPOINT but it is never used...yet. The ENTRYPOINT is an implicit run if it is the last line in the Dockerfile. That's there so I can "Run up to it" if I want to.

I can just build and run like this:

docker build -t podcast . docker run --rm -it -p 8000:80 podcast

NOTE/GOTCHA: Note that the "runtime" image is microsoft/dotnet:2.1-aspnetcore-runtime, not microsoft/dotnet:2.1-runtime. That aspnetcore one pre-includes the binaries I need for running an ASP.NET app, that way I can just include a single reference to "<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.0-rc1-final" />" in my csproj. If didn't use the aspnetcore-runtime base image, I'd need to manually pull in all the ASP.NET Core packages that I want. Using the base image might make the resulting image files larger, but it's a balance between convenience and size. It's up to you. You can manually include just the packages you need, or pull in the "Microsoft.AspNetCore.App" meta-package for convenience. My resulting "podcast" image ended up 205megs, so not to bad, but of course if I wanted I could trim in a number of ways.

Or, if I JUST want test results from Docker, I can do this! That means I can run the tests in the Docker container, mount a volume between the Linux container and (theoretical) Window host, and then open the .trx resulting file in Visual Studio!

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

Check it out! These are the test results from the tests that ran within the Linux Container:

Here's the result. I've now got my Podcast website running in Docker on an ARM32 Raspberry Pi 3 with just an hours' work (writing the Dockerfile)!

Cross-platform for the win!
