How to use .NET Core 2.0 ilasm.exe?

I'm trying https://www.nuget.org/packages/runtime.win-x64.Microsoft.NETCore.ILAsm/ (upon Where is ilasm.exe in Microsoft.NETCore.ILAsm?) on a Win 10 Pro x64 PC. Nothing happens.

Whatever syntax I'm using, still nothing. E.g. no .dll is generated from my input and nothing is printed in the console.

Even if I just run "ilasm" (no parameters), no output is produced. It remains completely silent. At the same time, if I run older C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\ilasm.exe, it always produces some output (for instance, parameter usage reference).

How am I supposed to use this latest ilasm.exe for .NET Core 2.0? Does it have different command line arguments? Or, maybe, I need some additional files for it to work (although the package didn't have anything meaningful but ilasm.exe itself)?

The .NET Core variants of ILAsm and ILDasm depend on core assets of the build of the same CoreCLR version they are built for. If they are restored via a dependency graph, a self-contained .net core deployment depending on Microsoft.NETCore.ILAsm should contain all assets for the target runtime.

To get the extracted version of ilasm.exe / ildasm.exe to work without doing that, you need to copy the coreclr.dll from the matching .net core version into the same directory. This file can be found in C:\Program Files\dotnet\shared\Microsoft.NETCore.App\2.0.0 if a .NET Core 2.0.0 runtime is installed in its default location.
