ASP.NET Core in .NET 6 - Part 01 - Overview

.NET 5 was released just about 3 months age and Microsoft announced the first preview of .NET 6 last week. This is really fast. Actually, they already started working on .NET 6 before version 5 was released. But it is anyway cool to have a preview available to start playing around. Also, the ASP.NET team wrote a new blog post. It is about ASP.NET Core updates on .NET 6.

I will take the chance to have a more detailed look into the updates and the new feature. I'm going to start a series about those updates and features. This is also a chance to learn what I need to rewrite, If I need to update my book that recently got published by Packt.

Install .NET 6 preview 1

At first I'm going to download ..NET 6 preview 1 from https://dotnet.microsoft.com/download/dotnet/6.0 and install it on my machine.

I chose the x64 Installer for Windows and started the installation

After the installation is done the new SDK is available. Type dotnet --info in a terminal:

Be careful

Since I didn't add a global.json yet, the .NET 6 preview 1 is the default SDK. This means I need to be careful if I want to create a .NET 5 project. I need to add a global.json every time I want to create a .NET 5 project:

dotnet new globaljson --sdk-version 5.0.103

This creates a small JSON file that contains the SDK version number in the current folder.

{
  "sdk": {
    "version": "5.0.103"
  }
}

Now all folder and subfolder will use this SDK version.

Series posts

This series will start with the following topics:

• Update on dotnet watch
• Support for IAsyncDisposable in MVC
• DynamicComponent
• ElementReference
• Nullable Reference Type Annotations

(I will update this list as soon I add a new post).
