Comment your dotnet restore command on dockerfile

#RUN dotnet restore

In my case a Post build event to xcopy files to my project folder leads to this error.

Just remove, build and run it and the error has gone. (right click on Project -> Properties -> Build Events) Afterwards add the copy command again and everything should work normally.
