WSFederationConstants.Parameters. Repeat Equivalent in WIF.NET 4.5

Question

I am trying to convert some code written in ASP.NET (with .NET version 3.5) that uses Windows Identity Foundation in MVC 5, which uses .NET 4.5

I found useful information about msdn here and here .

I have not yet found the equivalent of WSFederationConstants.Parameters.Result in .NET 4.5

What can be used for replacement?
