I start with Piranha for a week now, after read the documents and questions here I still can't solve the problem, so I post it here. Please help me. (I'm using Visual studio 2013 Update 2, Piranha 2.2.4)
I tested Piranha on the template project. Everything is fine, now I create a Telerik ASP.NET MVC Q3 2014 project and follow the "Getting started" tutorial to add Piranha to an exist project. I got this error message (I also applied this issue https://github.com/PiranhaCMS/Piranha/issues/277)
When I remove Piranha and Piranha.MVC reference and add references from source project I get this error

Please help me. Thanks a lot
Piranha CMS uses MEF to import extensions into the framework. There's been issues before that some other projects don't play to nice with MEF, maybe the Telerik stuff you're using has this issue.
There's a fix coming in 2.3 where you can tell the framework to only scan the Piranha assemblies for extensions which would probably fix your issues. I'll see if I can deploy a patch for this!
