I have a list called clients, when a new item is added to the list a new sub site should be created. I created an Azure Service Bus and copy pasted the ACS connection string for debugging.

I can debug the App Installed event without any problems, however when a new item is added to the list breakpoints are never hit.

I checked on Sharepoint Client Browser and the remote event receiver is there. http://screencast.com/t/OoPDhqRq

The code to add the RER and to execute the item added is here:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.EventReceivers;
using Capatech.IntranetWeb.Provisioning;
using System.ServiceModel;
using System.ServiceModel.Channels;

namespace xx.IntranetWeb.Services
{
    public class AppEventReceiver : IRemoteEventService
    {
        /// <summary>
        /// Handles app events that occur after the app is installed or upgraded, or when app is being uninstalled.
        /// </summary>
        /// <param name="properties">Holds information about the app event.</param>
        /// <returns>Holds information returned from the app event.</returns>
        public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
        {
            SPRemoteEventResult result = new SPRemoteEventResult();
            try
            {              
                switch (properties.EventType)
                {
                    case SPRemoteEventType.AppInstalled:
                        AppEvents.AppInstalled(properties);
                        result.Status = SPRemoteEventServiceStatus.Continue;
                        break;
                    case SPRemoteEventType.AppUninstalling:
                        //this.HandleAppUnInstall(properties);
                        result.Status = SPRemoteEventServiceStatus.Continue;
                        break;
                    case SPRemoteEventType.AppUpgraded:
                        AppEvents.AppUpgraded(properties);
                        result.Status = SPRemoteEventServiceStatus.Continue;

                }

I fixed it by moving the ItemAdded code from ProcessOneWayEvent to ProcessEvent and that's it.
