[davidbritch]

In .NET 9, a warning is produced for every binding expression that uses reflection. Therefore update all the samples in the 9.0 folder to use compiled bindings.

I'm especially interested in how to resolve these warnings for TemplateBindings, since I don't see anything about it on the docs

If you build the ControlTemplateDemos sample you will get the following warnings all from TemplateBinding's
