Description Alexander Köplinger [MSFT] 2017-03-10 18:13:50 UTC
Repro:

> public class A
> {
>     public static void Main(){}
> }

works (prints CS2002 warning):

> csc test.cs test.cs

fails:

> csc test.cs ../sourcefolder/test.cs
> test.cs(1,14): error CS0101: The namespace '<global namespace>' already contains a definition for 'A'

Tried with Mono master/d455c0d. Works with the csc included in .NET Core, so I assume it's our bug.
This turned up in the XA build today that Andi is trying to fix for 2017-02 (she'll deduplicate the files there for now).
