AppVeyor build is failing with error error CS1003: Syntax error, ',' expected

This issue has begun after this change in the history:

It is a valid change for Visual Studio but apparently AppVeyor is not accepting it, fixing this issue could be as easy as rolling back the change

@JoseASotoV Thanks for pointing this one out.

I fixed couple of them but apparently there are more. I will try to check Appveyor configuration, and hopefully there might be a better way of solving this.

I moved backend to Backbone project, need to check appveyor on that one:
