Can I have MVC and WebForms in the same Site/virtual directory?
I have a website running WebForms but I would like to implement MVC. Note: the website also have some Classic ASP files.
Yes, you can mix all in the same project.
See Plug-In Hybrids that shows how to mix all of technologies.
You can add MVC to existing WinForms application without problems. You may need to add IgnoreRoute rules for your existing pages. Classic ASP may need special handling (just potential - no idea about it really).
routes.IgnoreRoute("{myWebForms}.aspx/{*pathInfo}");
