Read Preamble Method
protected: void ReadPreamble();
protected void ReadPreamble ();
member this.ReadPreamble : unit -> unit
Protected Sub ReadPreamble ()
Notes to Inheritors
Classes that derive from Freezable should call the ReadPreamble() method before they attempt to access any members that are not dependency properties. The WritePreamble() method should be called before any such members are written to.
This method effectively does nothing more than call VerifyAccess().
