I updated MVC4 to MVC5. When you run the application I got an error that I don't have WebMatrix.Data. I installed it PM> Install-Package WebMatrix.Data. Now when you start getting in the browser:

Could not load file or assembly 'WebMatrix.Data, Version = 3.0.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35' or one of its dependencies. Located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Anyone know how to fix this?
