I had a operation contract with an int perameter, due to some reason I modified that to Guid and I update service refrence in client proxy project(it's in same solution).
But my client proxy is not update, it is still showing me the peramter as int. I also tried by deleting the service refrence and add service ref. again.
[OperationContract]
[TransactionFlow(TransactionFlowOption.Allowed)]
MembershipCreateStatus CreateUser(string application, string userName, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, Guid branchId, string branchName);
The branchId perameter was previously int.
