Created to test out the new Azure DocumentDb stuff. I used the standard Web Api template in VS 2013, swapping out the EF identity stuff for a DocumentDb backing store.
Also, a sample repository pattern that might work for such things.
To get start, go to the new Azure portal and create a DocumentDb instance. Open up the web.config and put the endpoint, auth key, and the name of the auth db in the app settings
NOTE: I have an issue with DocumentDb seeming to hang up when first creating a db or document collection. After the inital create is done it seems fine, but the request that created the db or collection never comes back. I have no idea what is causing that, but this stuff is pretty new right now.
