Compiler error Visual studio mac

Question

I'm working on Visual Studio for Mac preview. My project comes from a git repository and when i try to compile it, the compiler gives me this error:

Error: Error building target IncludeRoslynCompilerFilesToItemGroup: Item has already been added. Key in dictionary: 'Link' Key being added: 'Link' (NameOfTheProject)

I can't understand this error and i didn't find any resource about it on the web. Can you please help me? Thank you.

First thing I would try to do is to Clean/Rebuild the project. — Andrius, Nov 20 '16 at 17:02
It's a ASP.NET MVC web application with framework 4.5.2 @LexLi — Emanuele Clemente, Nov 21 '16 at 11:49
@EmanueleClemente then it won't work. Currently I think Microsoft has no plan to support .NET Framework stuffs on Mac. — Lex Li, Nov 21 '16 at 11:57
@EmanueleClemente I have the exact same issue that you are having. If you figure out a solution, could you let me know what you come up with? Thanks! — user1151295, Nov 21 '16 at 15:52
@LexLi But if i create a new MVC project it works. The error appears only on a project from a git repository. — Emanuele Clemente, Nov 21 '16 at 16:38
@EmanueleClemente because the VS 2015 template uses things that Mono does not fully support. VS for Mac does ship a suitable template, but I wonder if that's what you prefer. — Lex Li, Nov 21 '16 at 23:58

I have the same problem and the solution is just remove two references. like this

Microsoft.Net.Compilers

Microsoft.CodeDom.Providers.DotNetCompierPlataform

I found this solution at roslyn compiler not copied to AspnetCompileMerge folder using msbuild
