Entity Framework Core (EF Core) is a popular Object-Relational Mapper (ORM) framework for .NET applications. While primarily designed for relational databases, it has expanded its capabilities to support NoSQL databases, including MongoDB. This article will guide you through the process of using EF Core with MongoDB in your .NET 8 projects

Introduction

Before diving into the code, it's crucial to understand the nuances of using EF Core with MongoDB. Unlike relational databases, MongoDB is a NoSQL database, meaning it doesn't adhere to the traditional table-row structure. This introduces certain limitations and differences in how EF Core operates with MongoDB compared to relational databases.

In Part 1 of this series, I've explained the development environment setup for this article, that I will repeat here for the users who have not gone through it.

Before we start

In order to follow along with this articles, you will need:

.NET 8 SDK and .NET 8 Runtime installation

If you are planning to use Visual Studio 2022, make sure you have all latest updates installed (v17.8.2)

Install MongoDb Community Server, MongoDb Compass, and Mongodb version of Northwind database (Covered in this blog)

You may need Microsoft Azure (trial will also work) to setup Entra ID App in Azure and configure it to use

If you are fan of command line tools or want to know more about the tooling, see ASP.NET Core Blazor Tooling

How to setup MongoDB for development on windows

If you are not familiar with setting up MongoDB for development on windows, here is a quick walkthrough of what you will need:

Go to MongoDB download center and download MongoDB Community Server MSI package and install.

Next you will need MongoDB compass MSI and install it. You will need this tool to connect with your MongoDB Community Server and do the database administration related activities. If you are familiar with Microsoft SQL Server world, MongoDB compass is like SQL Server Management Studio of MongoDB world.

Next, download MongoDB Command line Database Tool which we will need to import an existing sample database.

We will be using a sample existing database called Northwind that I've downloaded from here

Import Northwind Mongodb Database

Open MongoDB Compass and connect to localhost:27017 which is a default port when you install MongoDB Server on windows.

Click on the databases in the left navigation and create a new database with name northwind and collection sample.

Go to github repository here in your browser, click on code in the top right and then download zip menu to download the zip file.

Extract MongoDB command line database tools zip file

Open mongo-import.sh inside the root folder and change the mongoimport keyword with the actual full path of mongoimport.exe that is part of MongoDb command line database tools zip file. The resulting line will look like below: "C:\temp\import\mongodb-database-tools\bin\mongoimport" -d "$1" -c "$collection" --type json --file "$file"

Open command prompt and go to root folder where you have mongo-import.sh file and run command ./mongo-import.sh northwind

If everything is done correctly, you will see console message that displays the json file name and the number of documents imported.

If you switch back to MongoDB Compass, select northwind database and click on the refresh at the top right corner of the sidebar, you will see collections like customers, employees etc.

We are going to use this sample database to build something interesting that makes sense and has a real-life use cases instead of just a sample table with a few fields.

Setting Up the Project

Create ASP.NET Core Blazor Server Web Application

Start visual studio and select create new project.

In the Create a new project window, type Blazor on the search box and hit Enter.

Select the Blazor Web App template and select Next.

In the Configure your new project window, enter BlazorAppPart4 as the project name and select Next.

In the Additional information window, select .NET 8.0 (Long Term Support) in the Framework drop-down if not already selected and click the Create button.

Build and run the application once so that you have your application url that you can copy from the browser and save it for later.

Add the nuget package 

Open Tools > nuget package manager > Nuget package manager console and type following command:

install-package MongoDb.EntityFrameworkCore

view rawPackageManager.ps hosted with ❤ by GitHub

This will install all the necessary files needed for accessing northwind database that we created in MongoDb using Entity Framework Core Code First.

Add Model for Customer table

In the example northwind database, there is already a customers table with some data in it. We are going to display the first name and last name of the customer. So, let's create a folder in the root called Model and add new file called Customer.cs that contains following class definition.

using MongoDB.Bson;

using MongoDB.Bson.Serialization.Attributes;

using MongoDB.EntityFrameworkCore;

namespace BlazorAppPart4.Model

{

[Collection("customers")]

public class Customer

{

[BsonId]

public int Id { get; set; }

[BsonElement("last_name")]

public string? LastName { get; set; }

[BsonElement("first_name")]

public string? FirstName { get; set; } }}

view rawCustomer.cs hosted with ❤ by GitHub

Create Entity Framework Core AppDbContext class

Next, we are going to create a new class called AppDbContext that inherits from DbContext class of entity framework core. Add another cs file called AppDbContext.cs in the models folder and paste following code.

using Microsoft.EntityFrameworkCore;

namespace BlazorAppPart4.Model

{

public class AppDbContext: DbContext

{

public DbSet<Customer> Customers { get; init; }

public AppDbContext(DbContextOptions options) :

base(options)

{

}

protected override void OnModelCreating(ModelBuilder modelBuilder)

{

base.OnModelCreating(modelBuilder);

modelBuilder.Entity<Customer>();

}

}

}

view rawAppDbContext.cs hosted with ❤ by GitHub

Create Customer Repository

Next, we want to use repository pattern to ensure data access code is separate and testable. Add another folder in the root of your project called Repositories and add a new cs file called ICustomerRepository.cs with below code:

using BlazorAppPart4.Model;

namespace BlazorAppPart4.Repositories

{

public interface ICustomerRepository

{

Task<List<Customer>> GetAllAsync();

}

}

view rawICustomerRepository.cs hosted with ❤ by GitHub

Once you are done, add 1 more file called CustomerRepository.cs with below code:

using BlazorAppPart4.Model;

using Microsoft.EntityFrameworkCore;

namespace BlazorAppPart4.Repositories

{

public class CustomerRepository : ICustomerRepository

{

private readonly AppDbContext _db;

public CustomerRepository(AppDbContext db)

{

_db = db;

}

public async Task<List<Customer>> GetAllAsync()

{

return await _db.Customers.ToListAsync();

}

}

}

view rawCustomerRepository.cs hosted with ❤ by GitHub

Create AppSettings.json settings

The AppDbContext context will require MongoDb connectionstring and database name. It is recommended to create an application wide setting section in the AppSettings.json. Open your AppSettings.json and 'AppConfig' section from below. I'm showing my full AppSettings.json file for your reference:

{

"AppConfig": {

"Database": {

"ConnectionString": "mongodb://localhost:27017",

"DatabaseName": "northwind"

}

},

"Logging": {

"LogLevel": {

"Default": "Information",

"Microsoft.AspNetCore": "Warning"

}

},

"AllowedHosts": "*"

}

view rawAppSettings.json hosted with ❤ by GitHub

Create AppConfig class for settings

Add AppConfig.cs class in your project and then add below code in the class definition:

namespace BlazorAppPart4

{

public class AppConfig

{

public AppConfig() {

Database = new DbConfig();

}

public DbConfig Database { get; set; }

}

public class DbConfig { public string? ConnectionString { get; set; }

public string? DatabaseName { get; set;

}

}

}

view rawAppConfig.cs hosted with ❤ by GitHub

Configure Dependencies in Program.cs

Next, we want to configure dependency injection so that Repository and AppDbContext classes that we created in our project can be injected where required. Here is my Program.cs:

using BlazorAppPart4;

Safeguarding Your ASP.NET Web Applications: A Deep Dive Into Security Considerations

In the ever-evolving landscape of web development, ASP NET web application security is of paramount importance. Microsoft’s ASP NET framework, renowned for its power and flexibility, lays the groundwork for dynamic and feature-rich web applications. However, this power comes with the responsibility of addressing potential security vulnerabilities. This article delves into crucial security considerations developers must prioritize in ASP NET web application development.

Authentication and Authorization: Authentication and authorization form the bedrock of web application security. ASP NET supports various mechanisms, including forms-based authentication and identity providers like OAuth. Developers must judiciously choose and implement the appropriate authentication method based on the application’s requirements. Proper authorization controls ensure that only authenticated users with the appropriate permissions can access specific resources.

InformationValidation: Attackers often target user inputs to exploit vulnerabilities. ASP NET developers must validate and sanitize all user inputs to prevent injection attacks, such as SQL injection and Cross-Site Scripting (XSS). Techniques like parameterized queries and encoding user inputs before rendering them on the client side significantly mitigate these risks.

Secure Data Transmission: Secure communication is imperative to protect sensitive data during transit. Utilizing HTTPS (SSL/TLS) encrypts data exchanged between the client and the server, preventing eavesdropping and man-in-the-middle attacks. Developers should enforce HTTPS for the entire application and configure secure communication protocols to enhance data integrity and confidentiality.

Cross-Site Request Forgery (CSRF) Protection: CSRF attacks exploit a web application’s trust in a user’s browser. ASP NET provides built-in mechanisms, such as anti-forgery tokens, to protect against CSRF attacks. Developers should incorporate these measures to validate the origin of requests and ensure that actions initiated within the application are legitimate.

Session Security: Sessions are crucial for maintaining user state, but insecure session management can expose sensitive information. Secure session handling practices, including unique session identifiers, session timeout mechanisms, and a secure repository of session data, are essential. Regularly rotating session identifiers add an extra layer of protection against session hijacking.

Error Handling and Logging: Effective error handling is vital for security and user experience. Carefully crafted error messages aid developers in identifying and resolving issues, while generic error messages presented to users prevent the disclosure of sensitive information. Proper logging mechanisms are equally important for tracking and analyzing security incidents for ASP NET web applications.

Secure File Uploads: File uploads can be a potential avenue for malicious activities. Developers must implement strict controls, including validating file types, restricting file sizes, and storing uploads securely. Utilizing content-disposition headers prevents browsers from rendering uploaded files as executable scripts.

Code Access Security: ASP NET incorporates Code Access Security (CAS) to control permissions granted to web applications. Developers should leverage CAS to restrict actions, ensuring applications operate within defined security boundaries. This granular control helps mitigate the impact of potential security breaches by limiting the scope of compromised components.

Regular Security Audits and Updates: The security landscape evolves, and regular security audits are crucial for identifying and addressing potential weaknesses. Staying informed about Microsoft’s security updates and promptly applying patches protects the application from known vulnerabilities.

In ASP NET web application development, security considerations are non-negotiable. Adhering to best practices in authentication, input validation, secure data transmission, and other key areas fortifies applications against potential threats. Establishing a robust security posture is not just a development best practice but a fundamental aspect of safeguarding user data and maintaining trust in an interconnected digital world. As technology evolves, so must our commitment to creating web applications prioritizing security without compromising functionality and user experience. Selecting an ASP.NET development company in India ensures a potent blend of technical expertise, cost-effectiveness, and skilled developers, making it a compelling choice for secure and innovative web solutions.

Small Business Website Development Tips: Navigating ASP.NET vs. PHP

In the rapidly evolving digital landscape, establishing a robust online presence is imperative for small businesses. The choice of a development framework plays a pivotal role in shaping the success of your website. Two widely used options, ASP.NET vs. PHP, offer distinct advantages and considerations.

Here are some small business website development tips for ASP.NET vs. PHP:
