Upgrading runtime and sdk and packages to .NET 6-CodePudding

I was following this tutorial on building an application with ASP.NET Core API and Angular where I used a laptop that had .NET 5 installed.

I got a new laptop and after I installed all the latest tools, I am now on .NET 6 and when I open my app to carry on where I left off, I get the following error when I run dotnet watch run in the VS Code terminal in the backend folder:

The framework 'Microsoft.AspNetCore.App', version '5.0.0' (x64) was not found.
  - The following frameworks were found:
      6.0.5 at [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=5.0.0&arch=x64&rid=win10-x64

Here are 2 screenshots showing what I have installed in this app from the time I was using it on my old laptop (now opening it and trying to run it on my new laptop)

Is there anyway I can cleanly update everything I need in one go, instead of installing .NET 5 or AspNetCore.App version 5.0.0 etc?

CodePudding user response：

Just correct the TargetFramework element's text content to net6.0.

Also update the NuGet packages.

Don't mind what's inside the bin and obj folders, whereas exist. Even better, make sure to Clean or Rebuild your project.
