TileLayer.Asynchronous Property
Gets or sets a flag indicating if data is read asynchronously by a background thread or not.
Syntax
public System.Boolean Asynchronous { get; set; }Property Value
Default: true
True if data is read asynchronously; otherwise, False.
Remarks
With this property set to True, presentation data for the tiles is read asynchronously from another thread. Updates only draw the tiles that have already been loaded. This generates a steady frame rate.
If the property is set to False, presentation is still read in tiles by another another thread, but during an update, the GUI thread waits for the background thread to load all needed tiles before drawing anything. This hides the tiling mechanism from the viewer, but will result in a lower and less predictable frame rate.
Note that if the update frequency is too high the thread that reads data might not get any time slices since it runs at a lower priority than the GUI thread.
