I'm following the advice in this post so that I can reference the HttpPostedFileBase class in a C# project. But when I add the System.Web.Abstractions.dll reference to my project the compiler still doesn't recognize System.Web.HttpPostedFileBase. When I go to the Class View > Project References > System.Web.Abstractions and click the triangle next to the dll I see no namespaces below it. It's appears as if my System.Web.Abstractions.dll is void of any content.
The path for the dll is C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web.Abstractions.dll.
Any ideas?
