Dotfuscator Professional Support for Microsoft Silverlight 1.1 Alpha

Cleveland, Ohio - July 10, 2007 PreEmptive Solutions, suppliers of a leading Enterprise Obfuscation Solution for the Microsoft .NET environment, announced today that Dotfuscator Professional 4.1 supports obfuscation of Microsoft Silverlight applications.

Silverlight developers now have the same patented protection against reverse engineering that the mainstream .NET development community has enjoyed since Dotfuscator shipped with Visual Studio 2003. A core component of Microsoft's overall strategy for the Web, Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of .NET-based media experiences and rich interactive applications. "Security is a major concern for customers whether their applications live on the Web or on the desktop," said Brian Goldfarb, group product manager of the UX Platform and Tools team at Microsoft Corp. "Dotfuscator Professional 4.1 with obfuscation support for Silverlight will help customers create rich, more secure user experiences."

Reverse engineering of managed code (including both .NET and Java) is a common practice and the associated risks are well understood. Because Silverlight 1.1 alpha applications run within an optimized .NET runtime, obfuscation should be used to protect Intellectual Property inside Silverlight applications and to prevent tampered Silverlight applications from being used to simulate, or interfere with web-based applications. "Dotfuscator Professional makes reverse engineering Silverlight applications materially more difficult," said Bill Leach, CTO of PreEmptive Solutions. "Further, Silverlight developers may find additional value in Dotfuscator's ability to compact, link and even watermark their Silverlight applications."

The Silverlight .NET runtime is optimized for the web; therefore, to ensure quality and portability, obfuscated Silverlight applications must be 100% standard IL AND rely solely on the .NET functionality supported in this special edition of .NET. "Our longstanding commitment to supporting the .NET development platform made Silverlight a priority and our deep expertise in the .NET runtime made it possible," said Gabriel Torok, President of PreEmptive Solutions.
