Unable to run dotnet-ilverify on Apple M1

[seesharper]

Description

Trying to install the global tool dotnet-ilverify on a Mac with Apple M1.

The tool installs just fine, but results in a System.BadImageFormatException when trying to execute.

Reproduction Steps

From the terminal

dotnet tool install dotnet-ilverify -g

Installs successfully

You can invoke the tool using the following command: ilverify
Tool 'dotnet-ilverify' (version '6.0.0') was successfully installed.

Expected behavior

To execute ilverify without any exceptions

Actual behavior

From the terminal

ilverify 

Result

Unhandled exception. System.BadImageFormatException: Could not load file or assembly '/Users/bernhardrichter/.dotnet/tools/.store/dotnet-ilverify/6.0.0/dotnet-ilverify/6.0.0/tools/net6.0/any/ILVerify.dll'. An attempt was made to load a program with an incorrect format.

File name: '/Users/bernhardrichter/.dotnet/tools/.store/dotnet-ilverify/6.0.0/dotnet-ilverify/6.0.0/tools/net6.0/any/ILVerify.dll'
[1]    58520 abort      ilverify

Regression?

Installing the 5.0.0 version of dotnet-ilverify works just fine

From the terminal

ilverify --version 

Result

5.0.0-rtm.20519.4+cf258a14b70ad9069470a108f13765e0e5988f51

Other information

Inspecting the two NuGet packages 5.0.0 versus 6.0.0 there is some difference in ILVerify.runtimeconfig.json

Contents of the file in the 5.0.0 package

{
  "runtimeOptions": {
    "tfm": "netcoreapp3.1",
    "rollForward": "Major",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "3.1.0"
    }
  }
}

Contents of the file in the 6.0.0 package

{
  "runtimeOptions": {
    "tfm": "net6.0",
    "rollForward": "Major",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "6.0.0-rc.1.21430.1"
    },
    "configProperties": {
      "System.Reflection.Metadata.MetadataUpdater.IsSupported": false
    }
  }
}

So the difference is that the 5.0.0 package targets netcoreapp3.1 while the 6.0.0 package targets net6.0
