I've been playing with Orchard for a few weeks and in have been getting on ok. I've just tried to deploy it to my shared hosting provider from scratch (which I have done once before), and I'm getting the following error:
The type or namespace name 'Mvc' does not exist in the namespace 'Orchard' (are you missing an assembly reference?)
I've checked the root bin folder and all the dll's I would expect are in there (including Orchard.Core, Orchard.Framework etc). I've tried to recycle the app pool a couple of times with no luck.
I've built my site from the full source zip file, used the VS2010 publish command (Release mode) to publish it to a local folder and then transferred everything using FileZilla. Everything transferred fine according to FileZilla, and the files look
fine fine on the server.
