ASP.NET Core post-publish not executed on Visual Studio Team Services

Question

I have a pretty weird problem with deploying my simple application to Azure as App Service. The application is ASP.NET Core and React front-end. The deployment flow looks like this:

• I code, commit and push to development branch
• Visual Studio Team Services picks up the changes and start building process: Build steps , example publish step log: log
• Then after successful build, the release process picks up the artifacts and start Azure deploy.
• As a result: all already had worked a few days ago, but now web.config is not transformed with IIS integration tools, so its being left in its pristine state:

  <!--
    Configure your application settings in appsettings.json. Learn more at http://go.microsoft.com/fwlink/?LinkId=786380
  -->

  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/>
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/>
  </system.webServer>
</configuration>

So, when you try to access the app service via url, it crashes with error 502 as a result. I verified by accessing the app service files and changing web.config by hand, that the application works fine with the correct web.config. My project.json:

        "Microsoft.AspNetCore.Cors": "1.0.1",
        "Microsoft.AspNetCore.Mvc": "1.0.1",
        "Microsoft.AspNetCore.Routing": "1.0.1",

        "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.1",
        "Microsoft.NETCore.App": {
            "version": "1.0.1",
            "type": "platform"
        }
    },

  "tools": {
            "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
                            "version": "1.0.0-preview2-final"
            } 
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "runtimeOptions": {
    "configProperties": {
      "System.GC.Server": true
    }
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "**/*.cshtml",
      "appsettings.json",
      "appsettings.Dev.json",
      "appsettings.Qa.json",
      "appsettings.Live.json",
      "web.config"
    ]
  },

  "scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

The thing is: when I publish the application locally with Visual Studio, all is well, the web.config is correct, the application works.

Finally, the question: what went wrong? In before, I would like to stay in this version of sdk, but if there's no other option I will consider updating. Thanks a lot for any suggestions!

Using Microsoft.AspNetCore.Server.IISIntegration.Tools 1.0.0-preview2-final instead. Related thread: Visual Studio Team Services asp.net core build for IIS
