Problems with deploy ASP.NET 5 (ASP.NET Core) app to Azure

Question

I have an app on ASP.NET 5 (CoreCLR) and I try to publish it to the Microsoft Azure. I using free Web App (not VDS)

I am publishing app using Visual Studio 2015 Publish->Microsoft Azureand following this instructions.

But when I publish it and try to open, I see just non-stop loading of empty page. I enabling logging and view the log (stdout.log) from Azure and there was only:

'"dnx.exe"' is not recognized as an internal or external command,

operable program or batch file.

Also I tried to do Continiusly publishing with git. During push, It started restoring packages and failed with error no disk space available.

Is there any way to publish ASP.NET 5 app to the Azure Web App?

Please post the key contents of your repository (e.g. project.json, startup.cs, web.config...) Then we can provide specific help. — Shaun Luttin

But when I publish it and try to open, I see just non-stop loading of empty page.

This happens when our app fails to publish the runtime (dnx.exe) with the application.

There are several ways to publish ASP.NET Core rc1 apps to an Azure Web App. These include continuous deployment with Git and publishing with Visual Studio. Post your repository's contents for specific help.

The example is an ASP.NET Core rc1 app, deployed to an Azure Web App, via GitHub continuous deployment. These are the vital files.

app/
    wwwroot/
        web.config
    project.json
    startup.cs
.deployment           <-- optional: if your app is not in the repo root 
global.json           <-- optional: if you need dnxcore50 support

app/wwwroot/web.config

Add the HttpPlatformHandler. Configure it to forward all requests to a DNX process. In other words, tell the Azure Web app to use DNX.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="httpPlatformHandler" 
           path="*" verb="*" 
           modules="httpPlatformHandler" 
           resourceType="Unspecified"/>
    </handlers>
    <httpPlatform 
         processPath="%DNX_PATH%" 
         arguments="%DNX_ARGS%" 
         stdoutLogEnabled="false" 
         startupTimeLimit="3600"/>
  </system.webServer>
</configuration>

app/project.json

Include a dependency on the Kestrel server. Set a web command that will startup Kestrel. Use dnx451 as the target framework. See below for the additional work to target dnxCore50.

{
  "dependencies": {
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final"
  },

  "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel"
  },

  "frameworks": {
    "dnx451": { }
  }
}

app/Startup.cs

Include the Configure method. This one adds an extremely simple response handler.

using Microsoft.AspNet.Builder;
using Microsoft.AspNet.Http;

namespace WebNotWar
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app)
        {
            app.Run(async (context) =>
            {
                await context.Response.WriteAsync(
                    "Hello from a minimal ASP.NET Core rc1 Web App.");
            });
        }
    }
}

.deployment (optional)

If your app is not in the repositories root directory, tell the Azure Web App which directory contains the app.

[config]
project =  app/

global.json (optional)

If you would like to target .NET Core, tell Azure that we want to target it. After adding this file, we can either replace (or complement) the dnx451 entry in our project.json with dnxCore50.

{
  "sdk": {
    "version": "1.0.0-rc1-update1",
    "runtime": "coreclr",
    "architecture": "x64"
  }
}
