Hi Denis,

Thanks for answer.

The third-party DLL I just link with early binding (including the reference in MS Visual Studio project).

Hi Kresimir,

I experienced a similar issue with pythonnet on the CPython side (import clr), but these could be unrelated.


How are you loading the third-party DLL? Did you check assembly binding log viewer for any errors?

We can't help much, if you cannot provide a reproducible code with all dependencies.

Hi all,

I use one third-party DLL (.NET) and after loading this DLL and then calling PythonEngine.Initialize() following exception will be thrown:

12/8/2016 1:05:34 PM: System.Reflection.ReflectionTypeLoadException Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information
bei System.Reflection.RuntimeModule.GetTypes(RuntimeModule module)
   bei System.Reflection.Assembly.GetTypes()
   bei Python.Runtime.AssemblyManager.ScanAssembly(Assembly assembly)
   bei Python.Runtime.AssemblyManager.Initialize()
   bei Python.Runtime.Runtime.Initialize()
   bei Python.Runtime.PythonEngine.Initialize()

If I first call PythonEngine.Initialize() and then call this third-party DLL, everything is fine.

The producer of this third-party DLL tells me the problem is not with them but with Python DLL.

Can somebody help me ?
