check if the Autofac.dll is in the referenced directory, the metadata warnings are ok to have them in Visual Studio 2012.
Make sure you have update 4 for VS 2012

I have managed to solve this problem. After upgrading from 3.30 to 3.40, I have also upgraded all the other extensions as well. There was one plugin which the author didn't update it yet. So, I removed it and uninstalled it since it is calling the old version of the dlls which is causing the conflict. It is also important to remove all the files in the release folders of all project, clean the solution and rebuild. This is how I solved my issue which takes lot of time to realize it.

I am still facing this problem please help, however I had uses the fresh code for 3.40 and tried to publish

Solved the problem, some DLL's in packages folder are blocked for some reasons.
What i tried is build Nop.Services, Nop.Web and plugin in Release mode and start to unblock corresponding dll

Hey guys, found this tip to unblock all files in a sub folder instead of unblocking all the problematic DLLs from the 'Packages' folder.

Here it is:

I did it in my project (version 3.30) and afterward, my publish worked like a charm, no more file locked and no more warnings.
Hope this helps.
