runtime: linux-arm runtime store is empty

Publishing a shared-framework app for linux-arm runtime from win-x64 will trim libraries that do not ship with the linux-arm 2.0.0 runtime. The app won’t run on the arm device.

Trimming is explained here and the ASP team strongly suggest the use of the Microsoft.AspNetCore.All to benefit from trimming.

The error output looks strange to me, as it includes x64 and x86 “stuff”, but I can’t interpret it. Fun fact: we don’t use appication insights (it is realllly difficult to opt-out) and the dll is not required anyways. Known workaround: disable trimming.

Steps to reproduce

• dotnet new web -o foo
• cd foo
• dotnet restore -r linux-arm
• dotnet publish -o deploy
• copy to the linux-arm device
• on linux-arm: dotnet foo.dll

Expected behavior

The application starts.

Actual behavior

The app crashes due to missing dlls. Sample output could look like this:

Error:
  An assembly specified in the application dependencies manifest (foo.deps.json) was not found:
    package: 'Microsoft.ApplicationInsights.AspNetCore', version: '2.1.1'
    path: 'lib/netstandard1.6/Microsoft.ApplicationInsights.AspNetCore.dll'
  This assembly was expected to be in the local runtime store as the application was published using the following target manifest files:
    aspnetcore-store-2.0.0-linux-x64.xml;aspnetcore-store-2.0.0-osx-x64.xml;aspnetcore-store-2.0.0-win7-x64.xml;aspnetcore-store-2.0.0-win7-x86.xml
