Could not load file or assembly ‘Microsoft.IdentityModel’

by gusse on October 11, 2011

I ran into this error here today Could not load file or assembly ‘Microsoft.IdentityModel’ working with the Microsoft CRM 2011 SDK.

The reason for receiving this error was because I did not have the Windows Identify Foundation Pack installed on my test computer where I tried to deploy the solution. So to fix this problem just download the msu file  (windows update file) and run it.

microsoft.xrm.sdk.dll’. —> System.IO.FileNotFoundException: Could not load file or assembly ‘Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35′ or one of its dependencies. The system cannot find the file specified.
