public virtual System.Threading.Tasks.Task WriteStartDocumentAsync ();
abstract member WriteStartDocumentAsync : unit -> System.Threading.Tasks.Task
override this.WriteStartDocumentAsync : unit -> System.Threading.Tasks.Task
Public Overridable Function WriteStartDocumentAsync () As Task
Returns

The task that represents the asynchronous WriteStartDocument operation.
