Alright, I've figured it out.

If you want to deploy a dotnet core app to Azure Web Service, include the runtime "win7-x86" if you are running your app in 32-Bit platform mode.

For a Visual Studio 2015 solution, your project.json should include :

  "runtimes": {
    "win10-x64": {},
    "win7-x86": {} //IMPORTANT FOR AZURE DEPLOY
  },

Or if you have already migrated to Visual Studio 2017, your .csproj should include this in PropertyGroup:

win10-x64;win7-x86

Also, your publish profile should include the same thing:

  
    FileSystem
    Release
    netcoreapp1.1
    bin\Release\PublishOutput
    win7-x86 // IMPORTANT
