On October 14th, 2014, Microsoft released several patches for ASP.NET. Three of these were for MVC, and they had some nasty side effects for the project I’m currently on. I will explain the three snags we hit with this update and how we solved them.
MVC solution won’t compile anymore
This is the most obvious of the three. After installing the update, we got all sorts of compiler errors, like:
Could not locate the assembly "System.Web.Mvc,Version=188.8.131.52, Culture=neutral, PublicKeyToken=31bf3856ad364e35,processorArchitecture=MSIL"
This error is sort of buried in all kinds of resulting errors:
The type or namespace name 'Controller' could not be found (are you missing a using directive or an assembly reference?)
