Please take a glimpse at the require/response information with Fiddler software.
The body content of the HTTP request and the fields of the transport can be set as shown in the screenshot above. For example, the SOAPAction field, please note that the namespace needs to be added. I suggest that you publish restful style WCF service, and then use httpclient httpwebrequest/webrequest build and send post/get request. See the link below.
How can I use a WCF Service?
