import non-WPF types into the markup

Recall that Xml Namespace declarations can be placed on elements in XAML to

import non-WPF types into the markup. The syntax is: xmlns:name=”clr-namespace:

clrNamespace;assembly=assembly.dll”. If the assembly is the

same as the one in which the XAML exists, you do not have to declare it.

The name “local” is commonly used in this scenario.
