Best Online ASP NET Courses and Programs

The web applications which are developed using the .NET framework or its subsets required to execute under the Microsoft Internet Information Services(IIS) on the server side. The work of IIS is to provide the web application’s generated HTML code result to the client browser which initiates the request as shown in the below diagram. ASP.NET is built on the CLR(Common Language Runtime) which allows the programmers to execute its code using any .NET language(C#, VB etc.). It is specially designed to work with HTTP and for web developers to create dynamic web pages, web applications, web sites, and web services as it provides a good integration of HTML, CSS, and JavaScript. ASP.NET is a server-side web-application framework designed for web development to produce dynamic web pages. It was developed by Microsoft to allow programmers to build dynamic web sites, applications and services.

It provides an interactive interface where you can access and interact with API endpoints directly in your browser. Additionally, Swagger automatically generates API documentation based on source code attributes and comments. Imagine the time it would take to create manual mappings dozens of times, plus the repetitive code that would be created.

DPA for ASP.NET Core applications

WebHostBuilder provides many optional methods including UseIISIntegration for hosting in IIS and IIS Express and UseContentRoot for specifying the root content directory. The Build and Run methods build the IWebHost that will host the app and start it listening for incoming HTTP requests. You can write your server side logic on any platform of your choice – it need not be – and call that API from the Blazor webassembly app . However, you will still end up creating mappers for client server communication classes.

  • Prior to ASP.NET 8, adding a parameterized authorization policy to an endpoint required writing a lot of code.
  • EF Core uses the concept of “model first,” where you define your data model using classes and properties in your code.
  • Environments, like “Development” and “Production”, are a first-class notion in ASP.NET Core and can be set using environment variables.
  • User authentication has already taken place at the beginning of the session.
  • It was developed by Microsoft to allow programmers to build dynamic web sites, applications and services.

Take some time to analyze what you need right now and in the near future. Don’t follow the trend without carefully analyzing your needs and what ASP.NET Core Identity can offer you. Perhaps the simple token format for the Identity API is enough for your needs.

Automatically Analyze ASP.NET Core Performance With Dynamic Program Analysis

When a browser requests an ASP or ASP.NET file, the ASP engine reads the file, executes
any code in the file, and returns the result to the browser. ASP.NET Core is designed to integrate seamlessly with a variety of client-side frameworks, including AngularJS, KnockoutJS and Bootstrap. The content root is the base path to any content used by the app, such as its views and web content.

This approach has been deemed excessive for small projects by several developers, and in any case introduces a third-party dependency that not everyone may want. Note that in the code above we are creating a string to store the database connection string. This example uses SQLite, an embedded, open-source, serverless relational database management system (RDBMS), and it is stored in the same directory as the application. We are also doing the dependency injection configuration through the AddDbContext() extension method.

In the context of ASP.NET Core, Swagger is commonly used to document APIs, allowing developers to easily and intuitively visualize and test the API. Note that in the code above we are passing the class to be validated to the “AbstractValidator” class. Then within the constructor we are creating validation methods for each of the properties that are mandatory, where, if they are null or empty, a message of error says they are mandatory. We also declare a method with the information to be recorded, which in this case will be the total number of products found in the database.

In the authentication and authorization context, a typical example of JWT adoption is when a third-party entity authenticates or authorizes a user. In this case, the third-party entity (the Identity provider or authorization server) issues a JWT containing the information related to the authentication or authorization result. This command will create a folder called “Migrations” which will contain the files with the instructions for creating the database and tables. Entity Framework Core (EF Core) is an object-relational mapping (ORM) framework developed by Microsoft.


The next step is to register the processes executed by the application so that it is possible to monitor and analyze the information. It supports multiple database providers including SQL Server, MySQL, SQLite, PostgreSQL and others, which means you can use the same EF Core API to interact with different databases. NuGet packages are a must for development, so let’s look at five of the essential packages for beginners and how to use them in an ASP.NET Core application. ASP.Net is built on the .Net framework to provide additional functionality around web development.

With AutoMapper, you can avoid writing repetitive code to copy property values from one object to another. It allows you to define mapping settings in one place and then use those settings to perform mapping automatically. A wide range of companies uses EF Core due to its sophisticated range of features that simplify data access and increase productivity when dealing with database operations.
