Hi,
Based on your description it seems you are using the __Prism for Windows Runtime__ version. If that is the case, this site is for the __WPF / Silverlight__ version of Prism only. The correct site to post this problem is:
* [Prism for Windows Runtime forums on CodePlex](http://prismwindowsruntime.codeplex.com/discussions)
If that is not the case and you are developing a WPF application, then take into account that __.Net 4.5.1__ and __Windows 8.1__ are not officially supported in this version and might not work correctly.
Regarding the exception you are mentioning, the image shows only a __Windows Azure's Mobile Services__ exception. It would be useful if you could provide more detail on this exception like the inner exception's details of where the exception is being thrown (in the corresponding forums.)
Thanks,
Damian Cherubini
