Hi 

Please refer-

Ensure that you have specified SOAP Action -

Also, confirm that the credentials you have supplied on the Port are correct.

Hi,

You need to specify your SOAP Action Header!

Refer similar thread: https://social.msdn.microsoft.com/Forums/en-US/a403d108-d6a8-4a34-9899-04b127a66031/biztalk-sned-port-with-wcf-custom-adapter?forum=biztalkgeneral

Hi Arindam

I tried the above mentioned method but still no luck...One more thing i want to add here is 
The xml i am sending is contains one envelop, body and Create tag which is correct but when i check in the admin console on that send receive port when the orchestration is in Dehydrated state message parts shows one more set of envelop,body and create tag inside the original tag.I am not able to understand from where these additional tag get attached to the xml at run time. 

And i am getting this exception now 

System.Net.WebException: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.

Thanxs

Ok, so firstly you should not be creating the SOAP envelope, or body in your orchestration. The message you construct should ONLY contain the Create record and its contents.

The WCF adapter will create the SOAP envelope and body for you. You only need to pass the Create element from your code.

Regarding the auth issue, I guess you have already created a separate thread for that.
