[MonoDevelop] Compiler Error

[Lilia Krause]

Hello,

I'm new by Mono. I downloaded MonoDevelop and I want to debug my Visual Studio project with mono because it should run on Linux. If I debug my project i get an error:

Error Fatal error BC2000 : unexpected error on compiler initialization: the project already contains a reference to the assembly "System.Drawing". It can't be added a second reference to "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Drawing.dll".

The error is in german. I've translated them for you.

Can you help me, please. I get no errors in Visual Studio, but I don't know where are saved this references.

Thanks,
Lilia Krause
