I've added the wildcard application mapping for c:\windows\microsoft.net\framework\v4.0.30319\aspnet_isapi.dll and unchecked the "verify that file exist" checkbox. This gives me GET and POST ability but not PUT and DELETE.
I have both prohibited and allowed WebDav under the web service extensions.
Application works like a champ when running in development environment. PUT and DELETE don't work when running app in IIS.
Any help is appreciated.
