`dotnet build` creating wrong executable name

[patrolez]

Hello everyone!

Problem

I have noticed that dotnet build results in exactly the same naming mistake as it was already mentioned in #1396, but I can reproduce the issue for dotnet build command, while publish command is producing correctly named executable.

Steps to reproduce

Just like in #1396, but with dotnet build instead of dotnet publish.
