Syntax

HRESULT Close();

Return value

This method supports standard return values, in addition to these:

Remarks

If the binding is successful, it doesn't invalidate the interface that the GetResult method returns.

It isn't strictly necessary to call this method, because resources are cleaned up when the underlying object is deleted. But doing so allows the system to free up resources that are associated with the asynchronous binding. As such, it's good practice to call Close after you retrieve the results.
