ASP.NET Core app on Ubuntu on Rasberry PI #1917

I've installed Ubuntu Core 16.04 on a Raspberry PI 3 and managed to get a .NET Core console app running on it by using the instructions here and using .NET Core version 1.2.0-beta-001291-00 which is compatible with ARM chips.

When I do the same with a basic ASP.NET Core app I get the following error :

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'System.Component.Primitives, Version=4.2.0.0, Cultire=Neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) at Microsoft.Extensions.FileProviders.PhysicalFileError.CreateFileWatcher(String root) at Microsoft.AspNetCore.Hosting.Internal.HostingEnvironmentExtensions.Initialize>(IHostingEnvironment hostingEnvironment, String appplicationName, String contentRootPath, WebHostOptions options) at Microsoft.AspNetCore.Hosting.WebHostBuilder.BuildHostingServices() at Microsoft.AspNetCore.Hosting.WebHostBuilder.Build() at Program.Main(String[] args) in /home/freek/aspnetcore/program.cs: line 12 Aborted

Here is the contents of program.cs :

using System;
using System.IO;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;

public class Program
{
  public static void Main(string[] args)
  {
    Console.WriteLine("Hello World API!");

    var builder = new ConfigurationBuilder()
      .SetBasePath(Directory.GetCurrentDirectory())
      .AddJsonFile("appsettings.json", optional: true)
      .Build();

    var host = new WebHostBuilder()
      .UseKestrel()
      .UseConfiguration(builder)
      .UseContentRoot(Directory.GetCurrentDirectory())
      .UseStartup<Startup>()
      .Build();

    host.Run();       
  }  
}

The code runs fine on a deskop with Ubuntu running .NET Core 1.1 but gives the error on a PI running .NET Core 1.2.0-beta-001291-00.
