Problem with program, "Cannot load assembly."

[Anonymous]

Hello, 

I put the first steps in . NET. I wrote a program "Hello world ", but when I try to run it in AutoCAD I get an error:

Cannot load assembly. Error details: System.BadImageFormatException: Could not 

load file or assembly 'file:///C:\Users\Dominik\documents\visual studio 

2010\Projects\Adsk\Adsk\bin\Release\Adsk.dll' or one of its dependencies. This 

assembly is built by a runtime newer than the currently loaded runtime and 

cannot be loaded.

Cannot load assembly. Error details: System.BadImageFormatException: Could not load file or assembly 'file:///C:\Users\Dominik\documents\visual studio 2010\Projects\Adsk\Adsk\bin\Release\Adsk.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

I use AutoCAD 2011, Windows 7, a program written in Microsoft Visual Basic 2010 Microsoft Expres.

I have  installed .net framework 4 Client Profile, .net framework 4 Extended and .net framework 4 Multi - Targeting Pack.

Any advice? Thanks for any help.
