Microsoft intermediate language (MSIL) Disassembler

The MSIL Disassembler is a companion tool to the MSIL Assembler (Ilasm.exe). Ildasm.exe takes a portable executable (PE) file that contains Microsoft intermediate language (MSIL) code and creates a text file suitable as input to Ilasm.exe.

This tool is automatically installed with Visual Studio and with the Windows SDK. To run the tool, you can use the Visual Studio Command Prompt or the Windows SDK Command Prompt (CMD Shell). These utilities enable you to run the tool easily, without navigating to the installation folder.

.NET runtime handling Generic code

Is there an ILDASM tool for dotnet 5 or 6?

The dotnet sdks for the "core" versions apparently have no ildasm tool. While the old Ildasm tool that shipped with dotnet 48 works with dotnet 6 assemblies I wonder if there is an Ildasm for dotnet 6.
