Getting a 404 when setting up MVC in IIS 6 and using .NET 4 beta 2
I have deployed ASP.NET MVC3 site to IIS6. I reinstall .net 4 and also installed asp.net mvc3 on that server. Added wildcard mapping as well c:\windows\microsoft.net\framework64\v4.0.30319\aspnet_isapi.dll
My web site uses windows authentication using active directory.
I am not sure what is causing this issue. I tried almost everything suggested online. But no luck.
