{
bool xAnythingHandled;
do
{

using (var xCtx = new DataContext())
{
foreach (var xEvent in (from item in xCtx.Events

break;
case "pullrequestevent":
HandleRetrievedPullRequestEvent(xCtx, xEvent, xPayload);
break;
default:
throw new Exception("Event not handled: '" + xEvent.Type + "'!");
}
}
//xEvent.Processed = true;
await xCtx.SaveChangesAsync();
// to handle:
//- PushEvent
//- PullRequestEvent
//xAnythingHandled = true;
