Why Use Asp.Net Core?

  • Cross platform:  It can run on windows, Linux and Mac.
  • Better performance: net core does not depend on system.web.dll for communication between Browser-server. In Asp.net core everything is packages which we need for our application. Packages reduce the request pipeline and improve application performance.
  • Dependency Injection:  Dependency Injection is in-built in Asp.Net Core.
  • Integration with Modern UI Frameworks:  It supports modern UI like Angular, ReactJS and Bootstrap etc.
  • Hosting-Net Core application can be hosted on multiple Web server such as IIS, Apache, Docker etc. It is not dependent on IIS.
  • Open Source:  It is a fully open source framework.
  • Testability:  Unit testing is very easy in Asp.Net core application.
  • Side-by-side App Versioning-Net Core runs on .NET Core, which supports simultaneously running in multiple versions of applications.
  • Unified Programming Model for MVC and Web API-In Asp.Net Core both MVC Controller and API Controller are Inherits from the same controller base class.

Setting up Machine for Asp.Net Core 5.0 development

 
We need to install 2 pieces of software for developing our Asp.Net core 5.0 application.
  • An Editor/ Integrated Development Environment (IDE)
  • .NET 5.0 SDK or Later (Software Development Kit)
Step 1 - Download and Install an editor for Asp.NET Core 5.0 Development
 
I am using Visual Studio 2019 updated version 16.8 or later as the editor for Asp .NET Core 5.0 application development. You can use any editor of your choice. 
  • Visual Studio
  • Visual Studio Code
  • Sublime
  • Vim
  • Atom
  • Etc.
Download and install Visual Studio
  • I am using Visual Studio 2019 16.8, so I need to install Visual Studio 2019 16.8 Community Edition because this is free.
  • You can download Visual Studio 2019 16.8 from this Link

Depending on the operating system you have, download and install the SDK.
  • The SDK includes everything you need to build and run .NET core applications.
  • The .NET Core Runtime is already included in the SDK. So, there is no need to install .NET Core Runtime
  • The .NET Core Runtime includes just the resources required to run existing .NET Core applications.
