David,
I have used Xenocode successfully for about 3 years now. Since I migrated my
app from VS .NET 2003 to VS2005, I upgraded my older Xenocode 2004 to
Postbuild 2007, the new name of the product.
Broadly, there are 4 features that you can use, namely: Symbol Renaming,
Control Flow Obfuscation, ILDASM Suppression and String Encryption. I found
that for my CF1 app (when it was in VS .NET 2003) that I could only use
Symbol Renaming and Control Flow Obfuscation. Both ILDASM Suppression and
String Encryption caused problems in my app and so I stopped using them.
After migrating my CF1 app to VS2005 (still using CF1 at the moment) and
Postbuild 2007, I have not had the time to see if ILDASM Suppression and
String Encryption still fail or not.
Hopefully this information my help you.
Regards,
Neville Lang
