Apple has announced plans to transition its Mac hardware line to a new Arm64-based chip that they refer to as “Apple Silicon”

.NET Core will be moving to support this architecture. ASP.NET Core will need this universal binary dotnet/aspnetcore#26821

Notes:

• Currently the RID for this architecture will be osx-arm64
• Cross compilation requires Xcode 12.2 or better
• Universal binary including arm64 is probably best. In which case arm64 needs to be added to the list of arches

I can prototype the changes to https://github.com/ericsink/cb is you would like.
