Metadata Collection is a set of information needed by WebFlyPostBackManager to perform FlyPostBack request. The information itself basically is a list of methods declaration (name of the methods, its parameters and its return value) for methods that marked as [WebMethod] or [WebFlyPostBackMethod].
This Metadata Collection by default is automatically retrieved during Page_Load. However, you can set the WebFlyPostBackManager to retrieve the Metadata manually by changing the AutoloadMetadata property to false. Retrieving the metadata collection manually means that collecting the Metadata only when a request is being sent for the first time.
