I have not tried Stacky in Azure so I can't really comment from experience on that.

I can say that the problem doesn't appear to be the assembly not being there. If, for example, the newtonsoft assembly was missing you would be getting an exception like:

>System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json, Version=3.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

Usually the exception you are seeing has more to do with assembly versions. Did you happen to update the version of the newtsonsoft assembly from the one which stacky references? You have to make sure to use the version that is bundled with stacky.

[This SO question][1] has a pretty good explanation of the problem.
