I needed to access .NET dlls compiled for .NET4 and ran into the error: System.BadImageFormatException: This assembly is built by a runtime newer than t he currently loaded runtime and cannot be loaded. (Exception from HRESULT: 0x801 3101B)
So I attempted to recompile PythonDotNET for .NET4. In VS2010 I changed all the project targets to be .NET4 and it compiled fine with only a couple of errors about System.Security.Permissions.SecurityAction.RequestMinimum being obsolete. Unfortunately when I tried to import clr I got the following error: SystemError: dynamic module not initialized properly Looking further into it I found that in buildclrmodule.bat lines 33 & 66 referenced the .NET2 idalsm.exe: %windir%\Microsoft.NET\Framework\v2.0.50727\ilasm /nologo /quiet /dll %ILASM_EXTRA_ARGS% /include=%INCLUDE_PATH% /output=%OUTPUT_PATH% %INPUT_PATH% I changed this to reference the .NET4 version: %windir%\Microsoft.NET\Framework\v4.0.30319\ilasm /nologo /quiet /dll %ILASM_EXTRA_ARGS% /include=%INCLUDE_PATH% /output=%OUTPUT_PATH% %INPUT_PATH% ...and everything works perfectly! HTH, Dave NB: Apologies if this appears twice - I sent it from a different account previously and don't think it made it through. _________________________________________________ Python.NET mailing list - [email protected] http://mail.python.org/mailman/listinfo/pythondotnet
