How to install .NET 2.2
Hello! 
I have tried to download .NET core 2.2 but can't get it to work. And because of that I get 
techy@vmi471392:~/miningcore/build$ dotnet Miningcore.dll -c config.json
It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.All', version '2.2.0' was not found.
  - The following frameworks were found:
      2.1.25 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.All]

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.All&framework_version=2.2.0&arch=x64&rid=ubuntu.20.04-x64



Is it possible to change what runtime version that is used?
