Got this error when copied ASP.NET MVC 2 RC application to shared hosting.

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterRoutes(RouteTable.Routes);
    }

Line 72 in Global.asax.cs is after >> RegisterRoutes(RouteTable.Routes);

Why is there reference to my local path on remote site?? D:\@Hemel\HemelMvc\src\HemelMvc\Global.asax.cs:72

Answer 1

Local path info is stored in the PDB file which helps the VS debugger help you. You don't need to include it on your host and you should switch your project configuration to "Release" so it does not include all the extra debugging info.

BTW you're probably getting the "could not load type" error because the shared host doesn't have MVC2 installed.
