Samples crashing SketchUp using Visual Studio 2015 express

Hi, I’m trying to get the sketchup SDK samples to work. I complied the skptoxml sample dll using VS 2015 express with no errors. But when I go to use it in sketchup, that causes a crash. Any advice would be appreciated.

Overall, it seems everyone is just using VS 2010 for their development efforts. Thats great, but I cannot find a working install of 2010 express anywhere. If someone could post a link, that would be helpful.

Moving to the SDK category. I think this has been asked here recently, Das.
