    How to prevent my .NET DLL to be decompiled?

    By design .NET embeds rich Meta data inside the executable code using
    MSIL.Any one can easily decompile your DLL back using tools like ILDASM
    ( owned by Microsoft) or Reflector for .NET which is a third party.
    Secondly there are many third party tools which make this decompiling
    process a click away. So any one can easily look in to your assemblies
    and reverse engineer them back in to actual source code and understand
    some real good logic which can make easy to crack your application.

    The process by which you can stop this reverse engineering is using
    "obfuscation". It's a technique which will foil the decompilers.
    There are many third parties (XenoCode, Demeanor for .NET) which
    provide .NET obfuscation solution. Microsoft includes one that is
    Dotfuscator Community Edition with Visual Studio.NET.
