I know that many of you were using eXpand modules for your XAF web applications for some time now and I want to thank you on behalf of the team for your feedback.

In this post, we will see how easy it is to create an XNA world for Windows Phone 7 that obeys the laws of physics. To our quest, our weapon will be the Farseer physics engine. You will be amazed when you realize how interesting a simple circle on the phone’s display becomes when you add some physics to its world! So let our quest begin… Download the zip file from the project’s site . Unzip its contents and locate the folder containing the sources of the Farseer engine (at the time of this writing the folder is named “Farseer Physics Engine 3.2 XNA”). Open Visual Studio and create a new project of “Windows Phone Game'” type ( important note: if you are a newbie in XNA game development you are strongly encouraged to follow this series of blog posts and also download the developer tools from here ). The game we will be making will be as follows: The user sees a sprite on the screen and it gives momentum to the sprite (yellow ball) by applying a gesture to the phones display. The sprite should be bouncing at randomly...

Lately, several posts (e.g. http://www.1800pocketpc.com/2011/01/09/windows-phone-7-3g-woes.html) were mentioning issues with overcharging related to cellular data connection usage of Windows Phone 7. From what I read later on, after looking into those incidents, Microsoft said that a certain popular application has been identified that was exchanging too much data without need and they’re working with its manufacturer [...]...

Some features are meant for the advanced users, some for the lazy. The mouse "Snap To" default button option is so poorly implemented (in Windows at least) that it is potentially dangerous. I enabled it for some testing. Later I......

What Locking is all about Transactional isolation is usually implemented by locking whatever is accessed in a transaction. There are two different approaches to transactional locking: Pessimistic locking and optimistic locking. The disadvantage of pessimistic locking is that a resource is locked from the time it is first accessed in a transaction until the transaction is finished, making it inaccessible to other transactions during that time. If most transactions simply look at the resource and never change it, an exclusive lock may be overkill as it may cause lock contention, and optimistic locking may be a better approach. With pessimistic locking, locks are applied in a fail-safe way. In the banking application example, an account is locked as soon as it is accessed in a transaction. Attempts to use the account in other transactions while it is locked will either result in the other process being delayed until the account lock is released, or that the process transaction will be rolled back. The lock...

If you’re developing a GPS enabled app for Windows Phone 7 you will surely appreciate the Windows GPS Emulator application. The Windows Phone GPS Emulator consists of a small WPF application and a WP7 DLL and allows you to create complex paths that you can play back just as if you were driving or walking. With it you can debug your application on the emulator or a real device without leaving the comfort of your home or office. Once you’ve completed your testing and debugging, you only need to change a single line of code to switch the device back to real GPS. The download includes: The Windows GPS Emulator application The Windows Phone GPS Emulator Client DLL A simple Windows Phone Test client An end-to-end Windows Phone App using Bings maps (a more complex sample) You can download it from APP HUB Oh how I wish I had a WP7 phone…...

When you work as a freelancer and are a father of two young boys it’s almost impossible finding a place at home where you can concentrate and work. So most of the times you end up at some local Wi-Fi enabled coffee shop enjoying a cup of coffee while tapping code on the keyboard. But what happens if you want to meet and talk with a client? So you can understand my excitement when I read about Joey’s discovery, Cloud Free Agent Espresso Bar , a place in Toronto Canada where you can have a coffee and work or host a business meeting if you have to. This got me searching through the internet to see if something similar was available in Greece and so that you know there’s actually a similar place in Athens Greece and it’s called coLabWorkspace . Although this place has a different business model from a coffee shop (coffee is free but you’re charged by the hour) and although it’s pretty expensive (in a coffee shop you can order coffee and sit there for hours, while in coLab you pay by the hour) can be used for the same...

In this post, we will see a simple implementation of a REST service.The service will consist of only one method and it can be consumed from your websites, directly from your browser or from a Desktop application. When implementing a service you need to specify the following: The service contract (the methods it offers). How do you know which one to access from the URL given (URL Routing). The implementation of the service. How you will host the service. Defining the Contract Create a new Class Library Project and call it “RESTService.Lib”. Add references to “System.ServiceModel” and “System.ServiceModel.Web”. Create an Interface class called IRESTDemoServices and add the definitions of the methods that represent the services offered. Our interface will offer just one service as follows: public interface IRESTDemoServices { string GetClientNameById( string Id); } In order to tell the framework to treat this interface as a service we need to decorate it as follows: [ ServiceContract...
