Hi

Been reading up on what the x: prefix in xaml really does. One comment I saw twice was - "x is used for mapping the XAML namespace in templates for projects." I find this a bit confusing. Is the namespace in templates? What templates? What is the relation between templates - namespace and projects? Don't we normally map something from one entity to another?

Then I get x:Name and x:Class but x:Key - Sets a unique key for each resource in a ResourceDictionary. Can I say that x:Key says use what is in the ResourceDictionary?

For example:

<Style x:Key="{x:Type TextBox}" TargetType="TextBox">...</Style>

x:Key says right go the the ResourceDictionary,
x:Type Textbox specifies which element in the ResourceDictionary we are referring to.

Am I correct?

Thanks.
