In one click you can reduce the size of your Silverlight apps up to 70% and secure your code with obfuscation. Add ComponentOne XapOptimizer to your dev cycle with build automation, backups, and limitless options.

Key Features:

Pruning: consists of analyzing the application and removing classes and resources that are not used. Dead code is common in applications that use libraries. Libraries typically include many controls and classes of which each client application only uses small subsets.
For example, if your application uses a C1HyperPanel, then it needs a reference to the C1.Silverlight.dll assembly, which contains the C1HyperPanel as well as many other controls your application does not use or need. In this case, XapOptimizer will create a new version of the C1.Silverlight.dll assembly that contains only the C1HyperPanel class and its dependencies.

ComponentOne XapOptimizer will also remove unused resources (Styles, Templates, Brushes, and so on) defined in resource dictionaries in XAML files. ComponentOne XapOptimizer supports merged dictionaries now as well.

Obfuscation: Obfuscation consists of changing the names of classes and fields in order to deter reverse engineering. This process also reduces the size of assemblies by using obfuscated names that are shorter than the original names.
For example, if your application has a public class called PasswordManager, the XapOptimizer obfuscator will rename that class to something more like x. This makes the new assembly smaller and harder to understand for anyone who opens it in a disassembler.

XapOptimizer is licensed the same way that the other ComponentOne development tools are licensed, which is per developer. Every Silverlight/Win Phone developer that would use this utility would need to purchase a licence.
