Now I have got this message

Warning There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "sfmlnet-window-2, Version=2.2.0.0, Culture=neutral, processorArchitecture=x86", "x86".

Is it a problem with the DLLs (the msg repeats for every DLL) or something in my VS 2015 project?
cos in VC# 2008 it ran perfectly ...
if the problem is in something about my VS 2015 project configuration, and someone who uses C# can tell me how to fix this, i would thank him/her strongly
