Thanks for sharing the information. It’s really useful. I tried with the instructions you have given and got the expected results.

When I exposed an orchestration as a wcf service, then also I was able to see the “WindowsUserName” in the context while debugging (using breakpoint).

But I was unable to access this property inside the orchestration. I tried by adding the reference to the propertyschema project and tried with below code:
msgResponse.UserName = WCFCustomProperties.PropertySchema.WindowsUserName;

When the orchestration project is compiled it is giving the error
“illegal use of identifier
‘WCFCustomProperties.PropertySchema.WindowsUserName’ in an expression”

Can you please help how to access this promoted property inside an orchestration expression shape.

Thanks
