As I said a while ago, Visual Studio 2015 appears to have lots of pretty serious bugs. One that probably bites me more than many people is this Save As bug. If you have a project and you select a file in that project and do a "Save As" such that the target file is also in the project then the VS2015 IDE crashes. I tweeted about this a while back, and the Visual Studio Program Manager, Cathy Sullivan, wanted me to create a new project and see if the problem happened with it... Not quite sure why she couldn't…
