Using C# Assembly in MATLAB

Hello everybody

I'm trying to work with C# assembly in MATLAB, so about my problem:

I created c# assembly with using third party librarys (Siemens.Engineering for work with their product TIA Openness).

And then I have problem with loading namespace and class in variable:

Message: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Source: mscorlib

HelpLink:

Then I wrote desifer LoaderExeption

try
    namespace.class
catch ex
end
ex.ExceptionObject.LoaderExceptions.Get(0).Message

And this give me more specific message:

Could not load file or assembly 'Siemens.Engineering.Contract, Version=1501.0.2801.1, Culture=neutral, PublicKeyToken=37a18b206f7724a6' or one of its dependencies. The system cannot find the file specified.

Look like assembly can't find this library. And this happen only if I have several methods witch use Siemens.dll.

But the mistery is, if assembly have only one method, it's work perfectly in matlab without any restrictions..

Maybe I need to load something like AssemblyResolve in MATLAB??
