ASP.NET Runtime missing from ARM32 tar.gz download on microsoft.com

see also dotnet/sdk#9360

If you do not install the dotnet SDK via dotnet-install (which I never thought of doing since that never did work in the past for ARM), you’d go to the download page for .NET Core and select Linux→ARM32 Binaries. This gives you a link to dotnet-sdk-2.1.300-rc1-008673-linux-arm.tar.gz.

Let’s list the contents and grep for AspNetCore

$ tar -tzf dotnet-sdk-2.1.300-rc1-008673-linux-arm.tar.gz | grep "AspNetCore"
./sdk/2.1.300-rc1-008673/Microsoft.AspNetCore.DeveloperCertificates.XPlat.dll

As can be seen from the output above, the ASP.NET Core runtime is missing. This causes the following error when attempting to run an ASP.NET Core application on ARM

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '2.1.0-rc1-final' was not found.
  - Check application dependencies and target a framework version installed at:
      /opt/dotnet/
  - Installing .NET Core prerequisites might help resolve this problem:

  - The .NET Core framework and SDK can be installed from:
      https://aka.ms/dotnet-download

@couven92 we haven’t released 2.1.0 RTM yet. Those links will update when we do 😃

This looks like a duplicate of https://github.com/dotnet/cli/issues/9162. Arm32 was fixed after rc1 with https://github.com/dotnet/cli/pull/9163.

Aspnet does not yet support arm64. See https://github.com/aspnet/Universe/issues/1117
