secure .net applications against disassembly

[Achim Kühn]

I´m planning to write a windows application using the .net framework. is
there any way to secure the application so the user can´t easily disassemble
and manipulate the application?

Visual Studio .NET 2003 ships with a the "Community" version of Dotfuscator
(Tools-->Dotfuscator Community Edition). This is a utility that will
obfuscate your IL code (i.e. make if very difficult to decipher once it's
been decompiled). There are other obfuscators available for .NET as well.

If you don't want users to "manipulate" your application, strong-name
it. See "Creating and Using Strong-Named Assemblies" in the help file.
That won't prevent them from reading the msil (obfuscation does that),
but it will prevent them from impersonating your app or introducing
hostile code.
