Q: 

C sharp asynchronous invocation with wsa replyTo

Hi,

I am trying to make an asynchronous call to a web service using BeginXXX and EndXXX methods from C sharp client. I am using a proxy class generated by using SvcUtil.exe.

The soap message that I expect to send should contain soap header elements for ws-addressing which include tags:

'wsa:Action'

'wsa:MessageID'

'wsa:ReplyTo'

'wsa:To'

However the soap header section is currently empty and only soap body contains body information.

Without the wsa tags, it looks like a synchronous call.

Is there a way to use proxy generated in c sharp, to invoke a service asynchronously such that the soap message contains wsa tags?

Appreciate any input with regards to this,

Thanks, Kavitha
