I have an webforms application configured under an MVC3 site in IIS 7.5. I’m ‘Could not load file or assembly…’ exceptions for System.Web.Mvc and System.Web.Helpers. When I add the MVC3 dlls to the webforms application bin directory everything works.
Why do I have to include the bin_deployable dlls in the webforms application?
You don’t have to “bin deploy”, unless the server you are deploying it to doesn’t have the assemblies in it’s GAC (usually true for shared hosting environments).
