Unable to run on IBM Cloud as Cloud Foundry App with Version 2.0.*

[Franklin89]

If I use the Packages with the Version 2.0.* I am unable to start the application as a cloud foundry app on the IBM Cloud. I get the following error:

If I explicitly set the version to 2.0.0 then everything works fine. I am using the IBM Cloud build toolchain for building and deploying the application. Is this an issue with the buildpack inside the cloud foundry?

Can we try this solution posted in the forums as a workaround.
aspnet/IISIntegration#476

Remarks from post:
The problem is the ASP.NET web app is using the host server package store and the IBM cloud build hasn't been updated as needed.

The solution is to add <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest> to your csproj files so the dotnet publish bundles all the required files

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest>
  </PropertyGroup>

Hope it helps!

This recommendation helped me overcome the issue described in this post (re: missing Microsoft.AspNetCore.Antiforgery.dll). However, I ran into another problem... I got "instance crash" errors when restarting:

APP/PROC/WEB --> bash: line 1:38 Killed dotnet <myapp.dll> --server.urls http://0.0.0.0:${PORT}

I think this is because I'm not explicitly stating the port my app should start on. Maybe missing a setting in class Program.BuildWebHost().
