DnSpy
dnSpy is a desktop application designed for the analysis, debugging, and modification of compiled .NET assemblies. It functions as an assembly analysis suite and decompiler, translating binary instruction streams back into readable source code to facilitate reverse engineering when original source files are unavailable.
The tool distinguishes itself through an integrated binary patching engine and metadata editor, which allow for the direct modification of executable logic and internal metadata tables. It supports in-process debugging instrumentation, enabling users to inject runtime hooks, set breakpoints, and inspect memory state within compiled binaries to troubleshoot application behavior.
Beyond core analysis and debugging, the platform provides an interactive scripting environment for automating repetitive tasks and manipulating assembly structures. It includes capabilities for abstract syntax tree manipulation and memory-mapped file inspection, allowing users to navigate between high-level code constructs and raw binary data.
