The dotPeak Free .Net Decompiler from JetBrains that decompile .NET assemblies into clean C# code or IL. This tool can decompile any .NET assembly into equivalent C# and optionally show the underlying IL code.
What is Decompilation
Decompilation is the reverse function of Compilation. Decompilation is the process of transforming a compiled binary executable/library into a higher-level symbolic language that is easier for humans to understand.
What is a Decompiler?
The decompiler function is the opposite of a compiler. A decompiler is a disassembling Software utility tool that takes an executable file (.exe) or library file (.exe) as input and attempts to generate a high-level source file that also can possibly recompile. All Decompilers may not perfectly reconstruct the source code correctly. However, they will frequently produce obfuscated code. Decompilers are one of the essential tools used in the reverse engineering of computer software.
What are the Decompilers on .Net?
.NET Reflector was the very first CLI assembly browser. It can be used to inspect, navigate, search, analyze, and browse the contents of a CLI component. It takes the input as any .Net compiled assembly and translates the binary information to a human-readable form. By default, Reflector allows the decompilation of CLI assemblies into C#, Visual Basic .NET, Common Intermediate Language, and F#.
In .Net, there are many free decompilers which alternatives to .NET Reflector. There are a few decompilers that provide the full features and are free. The free decompilers for .Net (free decompilers for c#) are ILSpy, JustDecompile (by Telerik), DotPeak (by JetBrains), DILE – Dotnet IL Editor (by zsozsop), etc.
dotPeak Free .NET Decompiler and Assembly Browser:
dotPeak is a free standalone tool from JetBrains that decompile .NET assemblies into clean C# code or IL. This tool can decompile any .NET assembly into equivalent C# and optionally show the underlying IL code. It is a free tool that allows developers to examine and analyze .NET assemblies, including both managed and native code. It can be used to decompile assemblies into C#, VB.NET, and IL (Intermediate Language) code, as well as to browse and search the code of the assemblies.
Uses of dotPeak
– Understand the code of third-party libraries.
– Recover lost or unavailable source code.
– Analyze assemblies to find potential bugs and performance issues.
– Explore the internal structure of assemblies and understand the relationships between different types and members.
– Compare different versions of assemblies to see what has changed.
– dotPeek can open assemblies that are stored on disk, in memory, and even as embedded resources. It also provides options to save the
decompiled code to disk, and to navigate to external sources and symbol servers when available.
dotPeak Free .Net Decompiler is a standalone tool and it does not require any integration with Visual Studio or other IDEs, it can be launched as a standalone application. It’s a great tool for developers that want to understand how a specific .NET library works or for developers that want to decompile their own assemblies to understand how they were built.
It allows developers to see the source code of any .NET assembly, including the ones you don’t have the source code for. This can be useful in a variety of situations, such as understanding how a third-party library works, troubleshooting issues with a deployed application, or recovering lost or inaccessible source code.
dotPeek can decompile any .NET assembly, including assemblies compiled with different versions of the .NET framework, and it can also decompile assemblies built with obfuscation. It allows developers to navigate and search through the decompiled code, as well as to view and edit the assembly’s metadata. dotPeek also allows you to export the decompiled code to a Visual Studio project.
It’s important to note that the decompiled code may not be identical to the original source code, and it may not include all the comments or original formatting. Additionally, many vendors or developers use the Obfuscation technique to protect the source code, in this case, the decompiled code may not be readable or understandable.
The dotPeak decompile below list of files:
- libraries (.dll), executables (.exe), Windows metadata files (.winmd)
- A compiled XAML file (.baml) Binary XAML file.
- dotPeek also opens archives (.zip, .vsix, or .nupkg) and folders.
- Load NuGet packages (and their dependencies)
dotPeak tool applications:
This tool is beneficial in the below list of scenarios.
Lost source code:
Suppose, assume that you have a .NET library (.dll) or .NET executable (.exe) for which the respective source code you have lost it. In this case, you can decompile the .NET library (.dll) or executable (.exe) and get the code back by using this tool. Further, you can save this code as a Visual Studio project (.csproj) file. Like this, you can save a lot of time restoring the lost source code from a legacy assembly and executable.
Cross check binary on-demand:
dotPeak Free .Net Decompiler tool is essential during any issue investigation to see the code modules directly from the deployed binaries. You can easily cross-check with the decompiled binary source code and investigate the issue.
