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.
ilasm
and ildasm
are available as nuget packages on nuget.org. Look for runtime.{RUNTIME_ID}.Microsoft.NETCore.ILAsm
and runtime.{RUNTIME_ID}.Microsoft.NETCore.ILDAsm
packages.
For example:
These contain executibles built for each specific .NET (and .NET Core) version for each platform.
