Hello,

I have Mathematica 7 and Visual Studio 2010 Professional edition. What I am 
trying to do is tho create a simple class in C# and use it in Mathematica.

In mathematica notebook I 've written the following code:
Needs["NETLink`"]
InstallNET[]

but when I try to load the assembly
LoadNETAssembly ["F:\\My\\Mathematica\\mLink\\mNETLink\\mNETLink\\bin\
\\Debug\\mNETLink.dll"]

I got this error

NET::netexcptn: A .NET exception occurred: System.BadImageFormatException: 
Could not load file or assembly 'file:///F:
\My\Mathematica\mLink\mNETLink\mNETLink\bin\Debug\mNETLink.dll' or one of its 
dependencies. This assembly is built by a runtime newer than the currently 
loaded runtime and cannot be loaded.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value 
[HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure 
logging.
To turn this feature off, remove the registry value 
[HKLM\Software\Microsoft\Fusion!EnableLog].
