Specifies if the user model differences are ignored.
true, if the user model differences are ignored, otherwise - false.
This property is set to false by default. You can pass the "-IgnoreUserModelDiffs" command line argument, when running a Windows Forms application, and this property will be set to true when instantiating the WinApplication. When set to true, runtime customizations are saved to the previous writable difference storage (Model.xafml, by default).
