به نظر من روش های و نرم افزار های قبلی خوب نیستند چون بیشترشون حجم فایل رو بالا می برن و کد خیلی هاشون رو میشه دوباره Disassmble کرد
خوب اینرا برا این گفتم تا یه برنامه جدید معرفی کنم قابلیت های کاملی داره و سازندگانش ادعا می کنند که فایل خروجی دیگه به وجود .NET Library محدود نیست ! و... کلی قابلیت دیگه که لیستش پایینه
سازندگان این برنامه یه نسخه رایگان هم برای آزمایش گذاشتن که می تونید برای تست ازش استفاده کنید !(آخه اگه باهاش برنامه تو پروتکت کنی موقع اجرا شدن پیام میده)و نرم افزارشون هنوز هک نشده!

Key Features Description
Application, Library and
Windows Service
Whatever your .NET product, .NET Reactor protects it.
Windows Windows Forms Applications, Console Applications, Windows Services, Control & Class Libraries, WPF Applications & Libraries Web ASP.NET Applications & Libraries, ASP.NET Services, WCF Services, Sharepoint WebParts Silverlight Silverlight Applications & Libraries Smart Device Compact Framework Applications & Libraries Others SQL Server CLR Assemblies, Mono Applications & Libraries .NET Reactor offers full protection support for your ASP.NET Applications and Libraries. .NET Reactor supports all .NET Framework implementations, including Compact Framework, Silverlight and Mono:
NET Framework 1.1/2.0/3.0/3.5/4.0
.NET CF 1.1/2.0/3.5
Silverlight 2.0/3.0/4.0
Mono 1.x/2.x
64-bit Support
.NET Reactor supports 32-bit and 64-bit Assemblies.
Merging/Embedding
.NET Reactor can merge or embed multiple .NET files into one executable(.exe) or library(.dll).
Compression
.NET Reactor is able to compress applications and embedded files up to 50-75%.
NecroBit IL Code Protection
NecroBit is a powerful protection technology which stops decompilation. NecroBit replaces the CIL code within methods with encrypted code. This way it is not possible to decompile/reverse engineer your method source code.
Anti ILDASM / Anti Decompiler
No tool can disassemble/decompile .NET Reactor protected code. ILDASM(the Microsoft Intermediate Language disassembler) will actually report that it cannot interpret .NET Reactor protected assemblies.
Native EXE File
.NET Reactor is able to generate a native x86 EXE file stub for your application. This way it is not possible to directly open your protected application in a decompiler. The decompiler recognizes your protected application as a native EXE file.
Pre-JIT Methods
In combination with the Native EXE File feature and NecroBit, .NET Reactor is able to convert managed methods into REAL x86 native code. Only methods which doesn't affect the runtime and platform behavior (mostly small methods like property getters/setters...) are converted into native code. By nature this feature has an built-in protection against assembly modification.
Obfuscation
In addition to source protection, .NET Reactor provides thorough class and member obfuscation complemented by different exclusion schemes, use of non-printable characters in obfuscated names, and even incremental obfuscation, which always generates the same obfuscation strings for type and member names.
Declarative Obfuscation
Declarative Obfuscation support allows you to directly define which types and members should be excluded from obfuscation. This can be done by using the custom attribute System.Reflection.ObfuscationAttribute in your source code. .NET Reactor automatically detects the attribute and excludes the corresponding types and members from obfuscation.
Control Flow Obfuscation
Control Flow Obfuscation converts the code inside your methods into spaghetti code, which whilst retaining the function of the code makes it extremely difficult for human eyes and decompilers to follow the program logic. Decompilers are not able to decompile the spaghetti code back to your original source code.
String Encryption
String encryption makes it difficult for a hacker to understand your code and to attempt a code patch of your assembly, as he will be unable to identify the text of messages or other useful strings, making it much more difficult to identify where to patch your code. This feature has a built-in protection against assembly manipulation.
Strong Name Removal Protection
Strong Name Removal Protection prevents your protected assembly from being tampered by hacker tools as they are not able to correctly resign the assembly with a different stong name.
Resource Encryption and Compression
.NET Reactor can improve protection and assembly size by compressing and encrypting your managed resources. At runtime, when required the resources are automatically decompressed and decrypted.
Powerful Licensing System
Powerful and flexible, the .NET Reactor licensing features allow you to enforce your license conditions and protect your revenue stream by using hardware and software locks. The license manager can build trial or permanent licenses, in a matter of seconds. A fully documented software development kit (SDK), complete with examples, allows you to call the licensing system directly from your code, allowing you to create custom extensions to the licensing system.
Third Party Support
.NET Reactor is a mature product which has attracted third party development of add-ons.
Full Language Support
.NET Reactor supports all types of managed assemblies (C#, VB.NET, Managed C++, ASP.NET, Delphi.NET, J#...).
Intuitive GUI
An intuitive, easy-to-operate GUI provides quick, comfortable operation.
