Can you try running dotnet restore and dotnet build?

Can you try running dotnet restore and dotnet build?

Sorry for being late.
So dotnet restore and dotnet build works on machine. Just can't build for docker.

Seems like something wrong in system itself since a machine is old one and some VSs, VSCs, .NETs were installed, uninstalled many times. There were no problems on laptop with only VSC installed.

Next text is about original old PC and Docker.
I tried to clean up, run the scenario and now it went this way. .NET is updated as it lived through Sep 24 patch tuesday.
