I have a question about how WINE processes marshalling between .Net Core code and COM object.
There is an application, which runs in x64 prefix. Application contains COM object and .Net Core user interface. Data between the com object and the UI are transmitted in structures, which contains safearrays of other structures, some of structures include BSTRs.
Some example of code is listed below:

Could you give me an advice of how to locate the reason of error and eliminate it?
