Upgraded project to Visual Studio 2010, but now get MVC error - asp.net

Question

I have an asp.net mvc 1.0 project. I upgraded the project and solution to Visual Studio 2010. However, I do not want to use asp.net mvc 2.0. My app compiles under mvc 1.0. All my references are to 1.0. I have copy local true and i am referencing mvc 1.0 from a lib folder, not the GAC.
However I keep getting this error:
No parameterless constructor defined for this object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.

Its like it wants to keep using asp.net mvc 2.0, because its complaining about that GetControllerInstance method.
This project works fine in vs 2008. wahhh! :(
Anyone? Anyone?
Thanks in advance.

Answer 1

I'm just trying to cover all the bases here, so forgive me if this is an obvious answer, but: Does PartingOut.Web.Controllers.HomeController actually have a parameterless constructor?

Answer 2

I figured it out.
Nothing to do with asp.net mvc 2 or vs 2010. It was still referencing asp.net mvc 1.0 fine. One of the other developers had done the upgrade and took out the "overrides" keyword in the method:
IController GetControllerInstance(Type controllerType)
on our own custom ControllerFactory.
Meh.
