To create a request-only (or one-way) webservice in BizTalk using the WCF-Service-Publishing-Wizard can be a little confusing at first.

After the first couple of screens, the wizard shows the screen below

You cannot delete the Response message. What you have to do is delete Operation1, then right click on the Service, select “Add Web method.”, then select “One-way” (instead of “Request-Response”, which was the original default.

Then you will have a one-way operation with only a Request method.

Other notes: Rename Service1 to some more appropriate name. It will create a file called xxxxxx.svc when the publisher has completed.
You can then add additional services if you want.
