Setting IIS7 Site Session State to State Server with MSbuild Extension Pack

Is there any way to choose the Session State Mode to be "State Server" when using MSBuild Extension Pack? I browsed the source co开发者_如何转开发de but there is no reference to state management.

Also, if anyone knows how to do this with the Extension Pack WMI that would be great too. I tried all kinds of queries and methods but couldn't come up with a way of talking to IIS through WMI to set SessionStateSection.Mode property "StateServer" flag as stated in MSDN.

Thanks...!
