Hi,

You may come across the below exception while generating wrapper classes using “crmsvcutil.exe” tool which comes along with CRM SDK.

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 specified

Reason :-

        The reason for this error could be the machine does not have “Windows Identify Foundation Pack” installed

Fix :-

• Download and install the Windows Identity Foundation Pack on the machine where you are trying to generate the wrappers.

Hope it helps 🙂
