Custom Action Result does not run ExecuteResult and just returns ToString
All of a sudden all of my RSS feeds stopped working on AlternativeTo. All I got was the name of the type I returned from my MVC methods that should return a “RssResult”. After some Googling, I finally found the answer on Stack Overflow as usual.
The problem was that I used version; MVC 2 in some of my projects (the one where the code for the Custom Action Result was located) and version MVC 3 in some others (the web project).
