Hi there -

you need to do 2 things in order to protect the app -

First - use licenses to secure the controls and the components that you're
distributing - there is a build in mechanism for this - for more info check
out
http://msdn.microsoft.com/library/de...tsControls.asp

Second - - obfuscate the assemblies in their final version with some
obfuscator (which will make the IL code unreadable) - check out
http://msdn.microsoft.com/msdnmag/is...ASP?frame=true
for more info

Hope that helps :)

You can use CrypKey to protect your .NET application, and use XenoCode
obfuscator to prevent reverse engineering of the MSIl.
If you are interested, you can contact me at CrypKey.
