Rollback framework from 4.5.1 to 4.0

Hi I have to recompile my website from framework 4.5.1 to 4.0.30319 because of what is installed on the webserver running iis 6.  When I select recompile the website and run it I am receiving a number of errors similar to this:

The type or namespace name 'Membership' does not exist in the namespace 'Microsoft.AspNet' (are you missing an assembly reference?)      C:\Users\Documents\Visual Studio 2012\Projects\RF\Account\OpenAuthProviders.ascx.cs

How do I either exclude these references or enable them to run on framework 4?  ~if possible?

don't think it is so easy to rollback beside you have a full backup somewhere.

however, your framework and iis 6 should be able to handle the issue. of course your code may not be dependent on new features coming with 4.5.1

Thanks sarbande, I removed the reference to:  Microsoft.AspNet.OpenAuthProviders in the package.config file then removed the .dll reference to this then removed all auto generated pages in the web app that had a reference to this namespace, thankfully hadn't used anything from it then reinstalled all nuget assembly packages to the right versions.  working now.  thank you for taking the time to respond.
