在Azure移动服务中添加新Controller时，Visual Studio 2015会冻结

Every time I right click the Controller folder and click add -> Controller, VS 2015 freezes. I am running on the latest win 10, VS is up to date and all the packages are the latest. I've tried different locations, checking permissions on the files and all types of other fun stuff. The weird part is that it only freezes on an azure mobile services project. If I do a web api project or mvc project I can add the controller just fine.Every time I right click the Controller folder
