Hi,
As far as I know, NCrunch hasn't been thoroughly tested yet on Azure cloud projects, but that isn't to say it can't be made to work on them. I'll see what I can do about looking at this use case in more detail to ascertain compatibility.
The 'csdef' file is a type of file that NCrunch hasn't yet been programmed to automatically detect. To work around this problem, try adding the following clause to your 'Additional files to include' under your project configuration: **.csdef
