<standardEndpoints> section cause webrole stuck at Busy state

<standardEndpoints> is the new added wcf configuration feature in .net framework 4. However, someone who utilize this config section in his/her webrole's config file may found that the application deploying on cloud would stuck at "Busy" state.

I consulted my colleague, and she me told that this is because the current cloud VM's (Windowss Azure Guest OS 1.4 (release 201005-01)) machine.config is missing the following section.

Adding this section at the beginning of your web.config file should fix this issue.
