when I use the dotnet command I have an issue

> dotnet Mydll.dll
It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '5' was not found.
  - The following frameworks were found:
      2.1.23 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      2.2.7 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      2.2.8 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      3.0.3 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      3.1.4 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      3.1.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      3.1.10 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      5.0.0 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      5.0.7 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.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.NETCore.App&framework_version=5&arch=x64&rid=win10-x64

I am a little suprised cause it seems I have the the runtime Microsoft.NETCore.App 5.0.0 installed and also the 5.0.7

Uninstall the deprecated package globally:

dotnet tool uninstall dotnet-ef -g

And then try to Reinstall the up-to-date package version:

dotnet tool install --global dotnet-ef --version 5.0.1 

If this does not work, try the second process:

So you have already installed .NET 5.

Download dotnet-sdk-5.0.301-win-x64.zip and copy the Microsoft.AspNetCore.App\5.0.301 folder manually from the zip file to C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App\5.0.301

Then the application should started working.

I had the same problem.

I added the following line to .csproj file manually:

<ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
</ItemGroup>

I had this kind of issue when trying to start my application from Visual Studio.

Updating Visual Studio using Visual Studio Installer solved this for me.

Direct download installer places the files in this folder

C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App

And Visual Studio installer places the files in this folder

C:\Program Files\dotnet\shared\Microsoft.NETCore.App
