Declares members implemented by Frame Templates.
NuGet Package: DevExpress.ExpressApp
The eXpressApp Framework design is based on the concept of abstract elements and actual controls. A Frame (Window) is an abstract entity. It can be displayed by any control. However, to support the relation with eXpressApp Framework elements, this contol must implement the IFrameTemplate interface.
IFrameTemplate interface has a descendant - IWindowTemplate, which declares members needed to display independent Windows.
