dotnet publish -f netcoreapp2.2 mysolution.sln should publish netcoreapp2.2 targets in solution but not generate errors for .netstandard2.2 projects in solution

Steps to reproduce

1. Create 3 projects
   • dotnet new classlib
   • dotnet new nunit
   • dotnet new console
2. Link all 3 projects into a .sln file (t.sln)
3. Both nunit and console project reference classlib as project reference
4. run: dotnet publish -f netcoreapp2.2 t.sln

Expected behavior

No errors, Netcore projects (nunit, console) publish to the publish folder for both projects. Class library does not publish, because -f netcoreapp2.2 was selected, not netstandard2.2. Also – dotnet publish -f netstandard t.sln publishes only the class lib with its dependencies. No empty classlib/bin/Debug/netcoreapp2.2 folder present During the build, a message is shown that project classlib is not being published, because it does not match the requested target framework type.

Actual behavior

Error message is shown in RED. Note that both netcore projects do publish correctly with the dependencies present. Empty ./classlib/bin/Debug/netcoreapp2.2 is created.

You can add

  <PropertyGroup>
    <IsPublishable>False</IsPublishable>
  </PropertyGroup>

To all these projects you don’t want to have published and should then be able to call dotnet publish -f .. on a solution. (or do it the other way round by creating a Directory.Build.props file setting it to False and then adding it with True to all your “entry point” apps)

Having the ability to skip netstandard targets, when you publish only netcoreapp framework, would come handy for automating builds. The need to specify a particular csproj file causes inconvenience.
