How do i save my code?
Thanks all...
You could use an obfuscation tool, like Dotfuscator or Eazfuscator.NET.
Eazfuscator.NET is free, Dotfuscator has a limited Community Edition, but is lacking many of the features available for free in the other product.
UPDATE
Eazfuscator.NET is now commercial. This link provides a download link for the last free version and lists some alternatives (as of September 2012)
