Answer 1

You can use the x:Shared attribute so that whenever something references the resource, a new instance is created instead of it being shared.

Thus you might have something like this:

<Window.Resources>
    <MyUserControl x:Key="MyControlKey" x:Shared="False" .... />
    ....
</Window.Resources>
