Asp.net core - hosting on Azure - asp.net

Question

UPDATED
I have published my solution to an azure web app. No errors arose, but when I browse to the page it doesn't display at all (a GET request is issued but the server does not respond for a long time and eventually returns a 500 error).
I think the problem might be that dnx is listening on http://localhost:5000, which is obviously not the Azure app site.
I deduced this by opening a Kudu debug console, and then running site\approot\web.cmd, which generates the following output:
info: Microsoft.Extensions.DependencyInjection.DataProtectionServices[0]
Azure Web Sites environment detected. Using 'D:\home\ASP.NET\DataProtection-Keys' as key repository; keys will not be encrypted at rest.
Hosting environment: Production
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.
But I can't work out how to change this. I have searched my entire source code and the environment variables, and the only reference to localhost is in Properties/launchSettings.json:
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:55071/",
"sslPort": 44391

Startup.cs includes the following code:
app.UseIISPlatformHandler(options => options.AuthenticationDescriptions.Clear());
web.config:
