What is decompiling and how is it done in C#?

Decompilation is the process used to produce source code from compiled code. In order to accomplish this we are partnering with ILSpy, a popular open source project, which provides first class, cross platform symbol generation and decompliation.

How do I protect my DLL from decompile?

Select only with “Anti IL Dasm” and “Anti Tamper”, that is enough for making it hard enough to reverse engineer for the decompilers. After you click on Done, go to Protect tab and click on Protect button. You can find the protected DLL or EXE in the output directory selected.

What is the meaning of decompile?

To decompile means to convert executable or ready-to-run program code — sometimes called object code — into some form of higher-level programming language that humans can easily understand. A decompiler is a computer program that receives input in the form of an executable file.

How do I decompile a DLL using net reflector?

NET Reflector VSPro into Visual Studio and open your project, then go to the . NET Reflector menu item and click on Choose Assemblies to Debug. Select the assemblies you want to debug, and . NET Reflector VSPro will immediately decompile those assemblies for you.

Can C# be decompiled?

Decompile .NET assemblies to C# It can reliably decompile any .NET assembly into equivalent C# or IL code. The decompiler supports multiple formats including libraries (.dll), executables (.exe), and Windows metadata files (.winmd).

Can DLL be decompiled?

Such a DLL is compiled to machine language and can only be directly decompiled to assembly language.

How do I protect a DLL file?

Keep the DLL in a resource and expose it in the file system (under a suitably obscure name, perhaps even generated at run time) only when running. Hide all real functions behind a factory method that exchanges a secret (better, proof of knowledge of a secret) for a table of function pointers to the real methods.

How do I turn off just my code decompilation?

In order to disable Just My Code navigate to Tools > Options (or Debug > Options) > Debugging > General, deselect Enable Just My Code. Decompilation will only generate source code files in C#. Try it now! Download the preview and try out decompilation and let us how it works for you!

What software do you use to prevent decompilation?

Writing on this thread after a long time. We have purchased a software called Intellilock which is helpful in preventing decompilation, obfuscation and also has a strong licencing module. We did not go for .Net Reactor even though it has more prevention controls as Intellilock was serving our purpose well enough.

What makes decdecompilers so good?

Decompilers take advantage of the adherence to these rules along with attached metadata to make decompilation much better than equivalent C++ decompilers. It’s hard to get into with a thorough understanding of IL, but basically each class in your code will end up having metadata.

How do I disable Just my code in Visual Studio?

In order to disable Just My Code navigate to Tools > Options (or Debug > Options) > Debugging > General, deselect Enable Just My Code. Decompilation will only generate source code files in C#.
