Google Analytics for Windows Forms applications? - winforms

I need to track usage statistics (such as which features are mostly used etc.) for my Windows Forms app that communicates with a WCF Service. Can anyone suggest how to achieve this using Google analytics? Also what is the best way to implement this, from the client app or the WCF service or both?

You can send data directly to Google Analytics using the Measurement Protocol.
The requests are sent via HTTP, so in terms of whether you should send it from the client or the server or both, the choice is yours. Do whatever is easiest.

Can I Use Google App Engine as XMPP Gateway

I have a Cloud App hosted on Windows Azure and I need to integrate XMPP with the service. Can I use GAE's XMPP API to achieve this? I'll need to be able to create new Jabber IDs and send & receive messages from other clients like GTalk.
As far as I know, GAE only supports Java, Python and my expertise is limited to .NET & C#; so, I'll have to make my Azure App to communicate with the GAE.
Finally, can I use GAE as an alternative to running ejabbered on Windows Azure Virtual Machines or Amazon EC2?
Thanks in advance... :)
You could but it would be very limited. You may be better off running ejabbered somewhere else.
With GAE's XMPP API, your username selection is rather limited. See the GAE XMPP Overview API documentation.
Your Cloud App would need to send and receive messages from your GAE app via HTTP accesses. This is no big deal for sending, but you'll have to work your own way of receiving messages. You could buffer your messages to the datstore and poll for messages. You could use the Channel API to receive messages directly, but so far the Channel API client is only available in Javascript, so your app would need some sort of javascript interpreter to use the client.
You will be able to send/receive messages from other XMPP addresses like GTalk clients.

Azure Web Site with Push notifications

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.

Does Google App Engine Support JAVA Proxy API's?

I have a question surrounding the REST service. I have an application written in C# , i want to put this application onto the cloud. I have a small problem, My Application has a built in C# API. I want to interact with my application and Google app engine. I want to develop a JAVA PROXY on top of GAE so that it can interact with my application using REST protocol and performs CRUD operations on Cloud and returns back data to my application.
Is it possible to do this ? to what i know is that SANDBOX feature doesn't allow us to directly interact with the App Engine.
Any suggestion on this.........
Thanks Heaps

You don't need Java Proxy API in order to make http requests to another server (I guess you did not have java's Proxy class in mind?).
Yes, AppEngine can make HTTP/REST requests to other servers via URL Fetch java API.

messages between local Silverlight apps without using local messaging

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.

Is it to possible create a simple chat facility using XMPP with Google App Engine?

I would like to create a web IM chat system using Google App Engine using XMPP possibly.
It would allow users of a social network to talk with each other.
Is this possible using GAE?
I haven't used GAE before. Does anybody know of any good examples/code which I could look into to get started?
If all your communication is between users who are interacting with your site directly, there's no need to use XMPP, or benefit from it - just write your IM system into the site directly. XMPP support is designed for interaction with external IM services.
Alternately, you could embed the Google Talk gadget in your site, but that will require users to sign in to their Google accounts to use it.
It's certainly possible. I would start with reading http://code.google.com/appengine/articles/using_xmpp.html in order to get started.
