Description

This extension provides support for WPF (Windows Presentation Foundation). The calculation of Automated Function Points for your .NET analyses will be supplemented through the creation of new objects and links specific to the WPF framework that will link back to objects/links produced by the base .NET analyzer.

In what situation should you install this extension?

If your .NET application contains WPF (Windows Presentation Foundation) source code and you want to view these object types and their links, then you should install this extension.

WPF framework support

The following WPF frameworks are supported by this extension:

Version	Supported
All versions up to 4.5

Function Point, Quality and Sizing support

This extension provides the following support:

• Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
• Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

Function Points (transactions)	Quality and Sizing

What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner. The following objects and links will be displayed in CAST Enlighten:

Objects

All objects are represented under the File browser  > Xaml Source file folders in CAST Enlighten as either WPF Custom Controls, or WPF Controls:

Icon	Object type
	WPF Control
	WPF Custom Control

Note that if the Name Attribute of an object is present, then it will be used to display that object in CAST Enlighten. For example:

Name not present	Name present

The following objects are detected:

Links

Source	Link type	Target	Example
XAML Control	call	Action Event method implemented in source file
XAML Control	relyOn	Set and get accessors of Property implemented in source file
XAML Control	relyOn	XAML Control which is used
XAML Custom Control	relyOn	XAML page that contains its definition
XAML Custom Control	relyOn	Defined Class
XAML Custom Control	AccessExec	Corresponding Property
XAML Custom Control	AccessExec	Corresponding Event handler function
XAML Source File	relyOn	Referred Class

Limitations

In this section we list the most significant functional limitations that may affect the analysis of applications using WPF:

• Binding in code is not supported - see https://msdn.microsoft.com/en-us/library/ms742863(v=vs.110).aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1 for an example

• Binding links are not handled correctly when the same binding target exists in different classes

• The direction of the data flow (Binding.Mode properties such as OneWay, TwoWay and OneWayToSource) is not supported - see https://msdn.microsoft.com/en-us/library/ms752347(v=vs.110).aspx#direction_of_data_flow for an example
• The RelativeSource property (Gets or sets the binding source by specifying its location relative to the position of the binding target) is not supported - see https://msdn.microsoft.com/en-us/library/system.windows.data.binding.relativesource(v=vs.110).aspx for an example
  
• Some XAML control objects which are visible in CAST Enlighten may not be seen in the CAST Engineering Dashboard.
• Links between XAML Control objects and code embedded in XAML are not supported.
