@ShonkyCH commented on Tue Mar 12 2019

/sdk/3.0.100-preview3-010431/AppHostTemplate/apphost

is an x86-64 binary:

ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=94bfae5d6580d203c7d9b4aa776ff09954453fff, stripped

I can repro by downloading the ARM SDK from https://dotnet.microsoft.com/download/dotnet-core/3.0, then running file on the apphost inside.

Downloading the runtime.linux-arm.Microsoft.NETCore.DotNetAppHost/3.0.0-preview3-27503-5 package Core-Setup produced, I see arm:

#> file apphost
apphost: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically
linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32,
BuildID[sha1]=d5b39d5d3f8fbee48b739d60a68b9b47fbe450b2, stripped

It seems something went wrong when Core-SDK consumed this package. Moving this issue there. (Unfortunately I don’t have admin powers for the smooth GitHub-supported move.)

@ShonkyCH I’ve confirmed that the latest nightly .NET Core 3.0 SDK builds available from the links on https://github.com/dotnet/core-sdk for both ARM and ARM64 have the correct apphosts now.

Additionally, the .version file in the sdk directory now shows the correct RID.

Please let me know if you run into any problems. Thanks!

Given the order of the options passed to build.sh, I think we can set _RuntimeIdentifier to linux-arm and linux-arm64 to override. A few other builds do so.
