title: Using Biztalk orchestration as a webservice
body: <p>I published an orchestration in Biztalk as a webservice. Does anyone know how I can use XML serialization or something  to load  XML from a file and "convert" it to the messagetype the webservice expects? How do people usually use this webservices? I try to avoid using untyped messages since I use both XML and flatfile, and have read that it could mean trouble.</p>
