dotnet run on macOS UX

Here's the current UX on macOS with the new x64 emulation capabilities. The installation is current (and totally) manual but the CLI experience works nicely for dotnet run.

App

rich@MacBook-Air-M1-2020 app % cat app.csproj 
<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

</Project>
rich@MacBook-Air-M1-2020 app % cat Program.cs 
using System.Runtime.InteropServices;

Console.WriteLine($"Hello, {RuntimeInformation.FrameworkDescription} on {RuntimeInformation.OSArchitecture}!");
rich@MacBook-Air-M1-2020 app % 

Dev UX

rich@MacBook-Air-M1-2020 app % dotnet run
Hello, .NET 6.0.0-rc.2.21452.13 on Arm64!
rich@MacBook-Air-M1-2020 app % dotnet run -a x64
Hello, .NET 6.0.0-rc.2.21452.13 on X64!

Magic

rich@MacBook-Air-M1-2020 ~ % cat /etc/dotnet/install_location 
/usr/local/share/dotnet/x64
arm64=/usr/local/share/dotnet
x64=/usr/local/share/dotnet/x64

Feel free to close this. There is no issue. Just sharing where we are at and what the magic is that folks need to make scenarios work.
