How can Dotfuscator®break ILDASM without adversly 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.
