Where *exactly* is MasterMessageItem defined?
Looking at the error, it seems to exist in App_Code\SiteMasterPage.cs. If that is indeed the only place it should be, then code in the App_Code should get built into an assembly named similarly to App_Code.dll, and you should *NOT* be seeing it in bin\EBS.Web.DLL.
If EBS.Web.Dll was compiled from a *separate* referenced project, then SiteMasterPage.cs should not be redefining it.
