How can Dotfuscator break ILDASM without adversely affecting the runtime?
There are known ways in which to break current versions of ildasm (the disassembler that ships with the .NET Framework SDK). Most of these methods rely on inserting invalid metadata into the application that the runtime does not use, but that the disassembler tries to parse. By setting this option, Dotfuscator Professional Edition will add such metadata to your application. When the disassembler tries to read the invalid metadata, it will crash. Note: The Break Ildasm feature will be removed from future versions of Dotfuscator. Newer versions of Ildasm are able to read the bad metadata Dotfuscator and other obfuscators introduce that cause Ildasm to break.
