LNK2028 LNK2029 when compiling static c++ library in managed c++/clr - c++-cli

Question

As i am pretty much out of ideas and the google results by now have reached the point where they hit ~10 and less, i now turn here in hope of seeing the answer or at least a clue that leads me to the actual solution.
I am creating a project that can be distributed as executable, non-static library and static library.
I want to use the library in a WPF project (C#) which is why i created a simple CLR wrapper.
It all worked very well up until the most recent change introduced into the base-library.
Now, i get linkage errors (5 in total) on all calls to the "main" class in the library project:

The projects, can both be found here:
The C++ Project https://github.com/SQFvm/vm
The C++/CLR Project https://github.com/SQFvm/ClrBridge
Was able to get rid of the LNK2028 issues by adding another separation layer (wrapper.cpp & wrapper.h) and then putting a #pragma unmanaged at the top of the cpp file.
Only the LNK2019 issues are left now

Answer 1

For those users who may find this question in the future, here is what helped me:
Separating all classes
Adding #pragma managed to the an unmanaged wrapper for the actual class (got rid of the LNK2028)
One of the following commits:
Moving invalidly placed C method out of external "C" that is not involved in any way normally to the static library built but MAY intefere with the CLR build process as the header still was there
Altering the arangement of the constructor
Hope this helps you.
