Project builds but can't publish

Question

I have an MVC project that for an uknown reason refuses to publish to a local folder in the PC.

The log says the following:

3>------ Publish start         


        

Answer 1

So I made it work.

The problem was the version of the "Microsoft.Net.Compilers". I downgraded from v2.6.1 to v2.4.0.

I don't know why so if someone knows it would be cool to know.
