.NET Decompiler with support for PDB generation, ReadyToRun, Metadata
...Visual Studio 16.3 and later include a version of the .NET (Core) SDK that is managed by the Visual Studio installer - once you update, it may get upgraded too. Please note that ILSpy is only compatible with the .NET 6.0 SDK and Visual Studio will refuse to load some projects in the solution.
Decompiler for setups creates with the Nullsoft Installer
...Attention this NSIS decompilation was disabled in 7z 15.06.
So last version that officially **supports NSIS Script decompilation** is 7z **15.05**
https://sourceforge.net/projects/sevenzip/files/7-Zip/15.05/ (2015-06-15)
-> 7-zip 15.10 no longer decompiles NSIS script
