This assembly is built by a runtime newer than t he currently loaded runtime

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.

Support for Python 2.6 & .NET 2.0
by Morne Joubert 19 Sep '10

The latest 2.5 binaries for .NET 2.0 works very well so my next question is about support for Python 2.6. All I need is the binaries (no installer needed). Can I create the binaries myself for 2.6 by compiling the source or could the 2.6 binaries for .NET 2.0 be added to the download section ? I only need very simple .NET 2.0 functionality.

New: Python 2.5 support
by Morne Joubert 11 Sep '10

Hi, I am totally new with Python and need some pointers on how to get Python 2.5 to call a .NET 2.0 assembly. I have been using the normal python distribution c:\python25 (using pyDev and Eclipse) I installed python .NET at C:\Program Files\PythonNet and then pointed pyDev at this folder but then it complained about language errors. I assume this is due to the differences between Python 2.3 and 2.5 So my question in a nutshell is.... What do I need to do to get Python 2.5 to call a .NET 2.0 assemble ? Do I need to somehow rebuild Python.NET ?
