dnSpyEx

dnSpyEx maintains the open-source dnSpy toolchain, a specialized IDE that lets developers de-compile, debug, and patch managed .NET binaries without source code or Visual Studio. Built around ILSpy’s de-compiler engine and the Roslyn compiler platform, the suite presents a familiar Visual Studio-like interface in which assemblies appear as fully browsable C# or Visual Basic projects, complete with syntax highlighting, call graphs, and metadata trees. Users can set breakpoints inside third-party DLLs, inspect live memory, manipulate IL instructions on the fly, and re-compile modified code back into a signed or unsigned assembly, making the software popular for reverse engineering, malware analysis, plugin patching, and rapid hot-fixes in production environments. Advanced features include a HEX viewer, memory dump importer, NuGet package analyzer, local variable re-naming, dark theme support, and BAML de-compilation for WPF resources, while extensible plug-ins allow scripting in C#, PowerShell, or IronPython. Compatible with Framework 2.0 through 4.x and .NET Core, the toolkit runs portably from a USB stick and supports x86, x64, and ARM64 processes, giving security researchers, QA engineers, and legacy-application maintainers a lightweight yet powerful alternative to heavyweight commercial disassemblers. dnSpyEx software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the newest build and permitting batch installation alongside other applications.
