In their own words
dnSpyEx
dnSpyEx is an unofficial continuation of dnSpy, a debugger and .NET assembly editor for working with assemblies without source code. It can debug .NET Framework, .NET, and Unity game assemblies, with breakpoints, tracepoints, conditional breakpoints, exception breakpoints, and multiple-process debugging. Editing covers metadata and methods or classes in C# and Visual Basic, plus low-level IL method bodies. The project lists C# and Visual Basic decompilers using the ILSpy engine, along with a BAML decompiler and disassembler. Assembly search, class and method usage analysis, caller finding, bookmarks, and project export are also included. A public API supports extensions, and the C# Interactive window can control or script dnSpyEx. The latest stable release listed is v6.6.0, which adds a .NET 10 distribution. It is free under GPLv3. Release notes describe Wine compatibility adjustments for Linux, not native Linux support. Dynamic methods cannot be debugged because of CLR limitations.
