Hi All,

I am trying to access CRM records by using WCF service.

I received the below error from a CRM WCF service that I created. 

Error:

The server encountered an error processing the request. The exception message is '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.'. See server logs for more details. The exception stack trace is:

    Hello,

    It may your local machine have identity foundation installed and it's not available on server or it may be corrupted. The exception clearly stating that it's not able to load identity foundation assembly.

    The exception message is '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.'. See server logs for more details. The exception stack trace is.

    Hope it will help.

    Thanks

    Hello Tin Latt,

    It's correct you are not having the WIF installed on the server.

    as suggested by the Guido and HIMBAP.

    make sure the assembly is present on the server as it's present on the local system.
