void WritePreamble();
protected void WritePreamble ();
member this.WritePreamble : unit -> unit
Protected Sub WritePreamble ()
Exceptions
The Freezable instance is frozen and cannot have its members written to.
Remarks
This method calls VerifyAccess to verify the threading context is accessible, and it throws an exception if the Freezable instance is already frozen.
Notes to Inheritors
Classes that derive from Freezable should call WritePreamble() before attempting to write to any members that are not dependency properties. If you call WritePreamble() in an API, you can omit a call to ReadPreamble().
