Solidwork API for unmanaged C++ code.

Hello,

We are using solidworks via the API in C# right now in our solution.  This solution is not very elegant for us because we need to make a bridge from unmanaged to managed code in our applications.  We are developing in C++ with visual studio 2010 x64.

Is there an API available that we could use directly from our c++ code with writing C# code?

Thanks,

Alexandre Fournier
