Publishing web services

The Invoke Web Service object builds an assembly at C:\ProgramData\Microsoft System Center 2012\Orchestrator\Activities\WebServices2or C:\Users\USERNAME\AppData\Local\Microsoft System Center 2012\Orchestrator\Activities\WebServices2. The assembly is identified by the web service location. For example, http://localhost/TestService/DylanService.asmx?WSDL.

If you publish additional services or update an existing service, you must clean the cache, except for the wspkey.snk file. After cleaning the cache, the web service changes are correctly published.
