This issue is related to the 32/64 bit differences between Matlab and Visual studio.

There is a workaround for this.

You can manage to get it working by changing your Visual Studio application properties "Platform target" to x64 and the target .NET framework to the Microsoft framework the .NET builder option.

If your "Plaform target" setting is set to "Any CPU", the "Prefer 32 bit" option under it must be unchecked for compilation to happen correctly.
