Unfortunately I'm having lots of issues with not found models like this on \App_Code\RazorHelper.cshtml :

The type or namespace name 'FaLinksPropertyEditor' could not be found (are you missing a using directive or an assembly reference?)

or this on the homepage: The type or namespace name 'Home' could not be found (are you missing a using directive or an assembly reference?)

I have excluded the models from the project, rebuilt, ... not sure what else. It was actually working and suddenly starts giving all these errors.

For Models Builders I'm using Dll.

Any ideas how to solve this?

thanks.
