kudu: Kudu can't deploy console app referencing netstandard packages

I’m unable to deploy a Console .NET Framework csproj (as a web job) if it contains a reference to a NuGet package that references netstandard2.0.

A repro repository is here: https://github.com/davidmatson/kuduissue2521repro

Here’s the error message I get:

Is Azure Web Apps currently running a preview version of .NET Core 2.0 tooling? I’m able to build locally when using VS 2017 Update 3 with the .NET Core 2.0 SDK (RTM versions of both).
