I am looking for a way to push notifications to a windows desktop app (a WPF app to be more specific) can I use azure notification hub for it? or are there any other alternatives out there?
It is not possible to use Azure Notification Hubs for this purpose. The core reason is that Azure Notification Hubs do not work with devices directly, rather it communicates via the Platform Notification Services for each platform (such as Windows Notification Service, Apple Notification Service, Google Cloud Messaging). And none of these services will work with a simple WPF application.
You have to design your own WPF Push Notification service via long polling or Web Sockets connection, and you could probably use Windows Azure Service Bus for that. But how to build such a service, is not subject to a SO question/answer.

I am new to Xamarin development.
I am building a Xamarin application with RESTful API and using SQL server for online storage and SQLite for the Local storage.
I need to add offline sync feature to my app.
Is there any way to sync remote server and local DB, without using azure mobile service client?
yes you can make use of Sync Adapter this would sync your data in background but this is Platform specific and hence you had to implement it in Native Class Also If you want a Periodic Sync you can also use JobSchedular in Android

I couldn't connect my iot device to azure iot hub to register device.
I saw some example in node.js and c# sharp client sdk. But I couldn't find for c sdk. Is it possible register device (obtain credential) from client side?
How can I connect my device to iot hub?
I tried to use this code:
https://github.com/Azure/azure-iot-sdk-c/blob/master/iothub_client/samples/iothub_client_sample_mqtt/iothub_client_sample_mqtt.c
Also I used this article for help: https://learn.microsoft.com/en-us/azure/iot-hub/iot-hub-device-sdk-c-intro
Very important: you don't want a device to create a new identity on its own in IoT Hub as that would mean that the device has credentials to manage the IoT Hub instance. This is a considerable security risk.
This is one of the main reason why we have 2 types of SDKs: service client SDKs and device client SDKs.
The service client SDKs are meant to be used in back-end applications that will manage the Hub, while the device client SDKs are meant to be used on devices. This allows to keep control of your IoT solution and prevent a rogue compromised device to start messing around with the other devices or your data.
You can actually find a C service client SDK in the C SDK repo under the folder "service" if you want to develop a back-end or management application in C.
Now, all that said, what it seems you are actually looking for is for a secure auto-registration mechanism, which is something we don't have yet on Azure IoT Hub. You can actually vote this feature up on uservoice here, as we are using this to help prioritize the upcoming features of the service.
I want to create a WCF Rest Application using NserviceBus and also i want use SQLServer transport.
Kindly help me ..Give me some Proper Code
NServiceBus V5.x - SQL Transport V2.x
The following sample shows you how to setup the SQL transport:
https://github.com/Particular/docs.particular.net/tree/master/samples/sqltransport-nhpersistence/Version_2.2
Hosting in IIS
NServiceBus can be hosted in IIS without any issues. Especially with a central broker transport like SQL, RabbitMQ, Azure Storage Queues or Azure Service Bus.
http://docs.particular.net/nservicebus/hosting/#self-hosting-web-hosting
NServiceBus can be hosted in any web technology that support .NET. This includes:
ASP.net
ASP.MVC
WCF
Web API
NancyFX
And many others.
As most web technologies operate in a scale out manner NServiceBus is usually hosted in a "Send-only" manner. In this mode they act as a "forwarder" of messages rather than the "processor". So the handling code (MVC controller, NancyFX module etc) of a given web request simply leverages the Bus send APIs and no processing is done in the web process.
Hosting in IIS does have some concerns as application pools by default don't startup automatically and can be recycled or even stopped. Any messages send to such an IIS hosted endpoint will not be processed until the application pool is started again.
MVC
The following samples demonstrate how to initialize NServiceBus and how to use it from MVC

I'm trying to develop a Windows Phone 8 app. I've created a Web Site in a Windows Azure account which is an MVC 4 project with REST endpoints. I've got an SQL database in Azure to store data from the Azure Web Site. Ocassionaly, I want my application to send PUSH notifications to mobile phones. So I've created a Mobile Service and I've linked the SQL database with the Mobile Service's database in order to have got the same data for the web page and the service.
I though that when I send an HTTP POST to the web site, the script in the database from the Azure Mobile Service would be launched but it looks not to be true. Isn't it? Because of that, I would write in the controller of an HTTP POST endpoint the code to send the data to the Mobile Service endpoint in order to launch the JavaScript code to send the Push Notification.
Is that the right approach for my goal? Is there any way for sending PUSH notifications from an Azure Web Site or it is only allowed from a Mobile Service?
My last question: Do you know any books or blogs about development in Windows Azure? On the Internet there is lots of documentation but principally those are get started tutorials. I've read some books but those are really complex, boring, and not really practical.
As your website MVC4 based and is running on Windows Azure using SQL Database as backend, I will guess that it is based on ASP.NET and i will write my suggestion based on that.
Now about your question "Is there any way for sending PUSH notifications from a Azure Web Site or it is only allowed from a Mobile Service?" I would say, Azure Mobile web services are designed for the same purpose for any service running on Windows Azure to send push notification on multiple of platforms. Application developer can choose to use Mobile Services to expedite their development as well as have multiple application using the one single service for such objective.
However as you mentioned "Is there any way for sending PUSH notifications from a Azure Web Site" this is not depend on "Azure web sites" instead it is depend on what development technology you are using with your Windows Azure Application. For example in ASP.NET your can use SignalR implementation if your application is based on Java, PHP, Python, Node,js etc then you can find some other run time specific real time implementation. If you look around for websockets you will find implementation in almost every popular language or look for comet programming on this regard. Not only that you can use some of the popular 3rd party applications for this purpose as well. i.e. pusher or any other.
While Windows Azure Mobile Services will give you the best results on Windows Azure platform as it is designed to provide such specific functionality for applications running on it.

I have one silverlight application hosted in HTTPS and another in HTTP. How can I send messages between them? Silverlight's local messaging system can not send messages between silverlight apps hosted in different URI scheme.
Silverlight's local messaging system typicaly uses for communication silverlight plugins on the same page. So, you provide more complex scenario. You access to first via https and to second via http, as I understant each application hosted in an own page and you want provide communication between this application. I think you should use services to synchronize their on server.
