    Hi Mohamed,

    Issue is related to CrmServiceClient  only but we fixed it in different way.

    Thanks for your reply

    Hi Prajwal,

    Can you put the line where you make the connection to crm as below and look if the error still occured :

    using (CrmServiceClient client = CrmServiceFactory.Get("myCRM"))

    {

       client.Something();

       client.SomethingElse();

    }

    Kr,

    Mohamed
