See here.
Two small problems - they work for ACS but not for Appfabriclabs and ,secondly, they don't work for people who have to work behind a proxy.
Some quick changes to the provided VS project should have you running in no time.
For Appfabriclabs:
In Constants.cs
//public const string AcsHostName = "accesscontrol.windows.net";
public const string AcsHostName = "accesscontrol.appfabriclabs.com";
For the proxy:
In ServiceManagementWrapper.cs - just add the proxy code below.
private string GetTokenFromACS()
{
var client = new WebClient();
WebProxy proxy = new WebProxy("1.2.3.4", 1234);
proxy.BypassProxyOnLocal = true;
proxy.UseDefaultCredentials = true;
client.Proxy = proxy;
client.BaseAddress = string.Format("https://{0}.{1}", this.serviceNamespace,
Constants.AcsHostName);
...
}
Then rerun the startHere.cmd to update and install the plugin.
Enjoy!
