How do we set ContentRootPath and WebRootPath?

Question

We're ending up with the following ContentRoot and WebRoot when we run our app from IIS.

ContentRoot:  C:\MyApp\wwwroot
WebRoot:      C:\MyApp\wwwroot\wwwroot

Here is how we are setting ContentRoot and WebRoot.

public class Startup
{
    private readonly IHostingEnvironment _hostingEnv;

    public Startup(IHostingEnvironment hostingEnv)
    {
        _hostingEnv = hostingEnv;
    }

    public void Configure(IApplicationBuilder app)
    {
        app.Run(context =>
        {
            // test output
            context.Response.WriteAsync(_hostingEnv.ContentRootPath + "\r\n");
            return context.Response.WriteAsync(_hostingEnv.WebRootPath + "\r\n");
        });
    }

    public static void Main(string[] args)
    {
        var contentRoot = Directory.GetCurrentDirectory();
        var webRoot = Path.Combine(contentRoot, "wwwroot");

        var host = new WebHostBuilder()
            .UseKestrel()
            .UseIISPlatformHandlerUrl()
            .UseContentRoot(contentRoot)  // set content root
            .UseWebRoot(webRoot)          // set web root
            .UseStartup<Startup>()
            .Build();

        host.Run();
    }
}

From intellisense I see that...

• ContentRootPath contains the application content files.
• WebRootPath contains the web-servable content files.

How do we make the test output look instead like this:

ContentRoot:  C:\MyApp\
WebRoot:      C:\MyApp\wwwroot\

While RC2 documentation is still being prepared, here is what I learned while trying to deploy pre-RC2 app as Azure Web App:

1. There is no Visual Studio tooling yet, so the app must be published and deployed manually over FTP. For publishing, use: dotnet publish --configuration Release --output ./approot

2. If connected to Azure over FTP, you will probably see something similar to:

3. The "approot" folder can be replaced with the published one (the web.config is left in the approot).

4. The "approot" must be configured as a virtual application in Azure Portal (the default was site\wwwroot):

5. An the last thing to get static files served from the wwwroot folder, the Startup.cs file should be modified to include custom UseWebRoot call:

var currentDirectory = Directory.GetCurrentDirectory();

var host = new WebHostBuilder()
    .UseKestrel()
    .UseWebRoot(Path.Combine(currentDirectory, "..", "wwwroot"))
    .UseDefaultHostingConfiguration(args)
    .UseIISIntegration()
    .UseStartup<Startup>()
    .Build();

After these steps you should have ASPNET Core pre-RC2 web app running on Azure.

In RC2, if we put the web.config beside wwwroot and point IIS at the MyApp directory like this...

MyApp
  web.config
  wwwroot

...the code from the original question outputs this...

ContentRoot:  C:\MyApp\
WebRoot:      C:\MyApp\wwwroot\
