The record

Purpose: dnSpyEx is an unofficial continuation of dnSpy, a debugger and .NET assembly editor for working with assemblies without source code.
Debugging: It can debug .NET Framework, .NET, and Unity game assemblies, with breakpoints, tracepoints, conditional breakpoints, and multiple-process debugging.
Assembly editing: It supports editing metadata and methods or classes in C# and Visual Basic, as well as low-level IL method-body editing.
Decompilation: The project lists C# and Visual Basic decompilers using the ILSpy decompiler engine, plus a BAML decompiler and disassembler.
Analysis tools: Features include searching assemblies, analyzing class and method usage, finding callers, bookmarks, and exporting to a project.
Scripting and extensions: A public API supports extensions, and the C# Interactive window can be used to control or script dnSpy.
Integrations: To debug Unity games, the project says the dnSpyEx Unity Mono repository is also needed.
Current release: The releases page lists v6.6.0 as the latest stable release and says the release adds a .NET 10 distribution.
Platform support: The v6.6.0 notes describe Windows 11 Snap Layout support and Wine compatibility adjustments for running dnSpy on Linux; they do not describe native Linux support.
Security and integrity: The v6.6.0 release lists SHA-256 hashes for its ZIP distributions and says the release commit was signed with a verified committer signature.
Limits: The project notes that dynamic methods cannot be debugged because of CLR limitations.
License: The repository states that dnSpy is licensed under GPLv3.
Maintainer support: The v6.6.0 release notes direct users of third-party extensions to their extension developers for help with extension issues.
Price from: Free
