ASP.NET MVC stopped working after updating application - got problems with MembershipUser

Today I updated my application to the latest versions. Now at this code:

Membership.GetUser();

I get following error:

Method not found: 'System.Data.Objects.ObjectContext System.Data.Entity.Infrastructure.IObjectContextAdapter.get_ObjectContext()'.

I know that the update has changed my web.config - maybe it's because something is wrong in this file now?

Solution

  • Looks like this is caused by the package Microsoft.AspNet.Providers.Core v. 1.2. I uninstalled it and then installed version 1.1. If you are also using LocaDb, you have to uninstall LocaDb package since it depends on Microsoft.AspNet.Providers.Core. You'll have to reinstall LocaDb afterwards.

    Grab v. 1.1 using the NuGet Package Manager Console within Visual Studio:

    Install-Package Microsoft.AspNet.Providers.Core -Version 1.1
