want to implement the IControllerFactory interface but
not in the MVC framework generated web
application. The implementation would exists in another class library. I set a reference for the System.Web.Mvc
dll and also to the System.Web dll (which holds the
System.Web.Routing.RequestContext which is needed
for the CreateController method.
I finished to implement the interface and
compiled the solution. A very strange “does not
implement interface member 'System.Web.Mvc.IControllerFactory.CreateController(
error message is jumping at me from the Error List View. Since I know that I finished to implement all the methods
in the interface this error is very interesting and annoying.
I searched the web for indications about this error and found some
references without any solution such as this post.
I tried to figure out what was missing. So I
guessed that I wasn’t referencing another assembly which causes
the inappropriate error. My first guess was the System.Web.Routing
dll. I referenced it and the build succeeded without any errors.
Sometimes more informative errors can help you to find the problems you face. In this case the error wasn’t helpful and lead me to think that something in my implementation was wrong. I hope that this post will help you if you get stuck with this error.
