Choose Language for classes after abinary dotNet reverse engineering

[TReichert]

When I reverse a dotNet EXE all the classes are C#, regardless of the language defined for the model.
Filename is set to the DLL, that was used for reverse enginering.

Both is not usefull for code generation.

When I correct this properties for an individual class, code generation works fine.

But I import hundreds of classes, so it is undesirable to modify the properties of each class manually.

How do I import a dotNet  binary, so I can generate C++ files from the classes the reverse engineering created.

Thank you
