Error when running the game on Linux

I started a new linux game project on Visual Studio 2013 and coded the game. It’s run correctly on Windows, but when running it on linux, I get this error:

Missing method .ctor in assembly /home/user/game/VectorZ_Linux.exe, type System.Runtime.CompilerServices.ExtensionAttribute
Can't find custom attr constructor image: /home/user/game/VectorZ_Linux.exe mtoken: 0x0a000011
* Assertion at class.c:5597, condition `!mono_loader_get_last_error ()' not met

Any ideas?

up… Any ideas?..
