Using the Entity Framework 4.3 in .NET Development

This article describes how to use the Entity Framework for building applications through a tutorial. The Entity Framework enables developers to create data access applications by programming against a conceptual application model instead of programming directly against a relational storage schema. The goal is to decrease the amount of code and maintenance required for data-oriented applications.

The end product will be a group of unit tests that use the Entity Framework to query and update the database. This code can be used in your data-oriented application for data access and updates. No ADO.NET code is used to communicate with the database. The objects that are returned are enumerable types that can be traversed using LINQ.

A N-Tier Architecture Sample with ASP.NET MVC3, WCF and Entity Framework

N-Tier software architecture can solve the following client/server system issues: scalability, security, fault tolerance and etc. In our previous article "N-Tier Architecture and Tips" we introduce the basic N-Tier architecture concepts and some practical tips. In this article, we try to elaborate a N-Tier architecture sample with ASP.NET MVC3, WCF and Entity Framework. In Java, usually there is a pre-defined way to achieve the N-Tier architecture: J2EE architecture, which uses session bean over entity bean for business and persistence layer, Java bean, servlet or JSP for the client presenter layer, Java Swing, HTML or applet as the client side. Therefore, for J2EE, different application are very likely implemented in very similar ways. However, in .NET, even though there are many tools and features available, there isn't any pre-defined way as J2EE does to guard how to implement the N-Tier architecture. As a result, there are too many inconsistent and existing ways to do this. Some are good; some are bad. This article tries to introduce a decoupled, unit-testable, deployment-flexible, implementation-efficient and validation-flexible N-Tier architecture in .NET. What we achieved here is to put some well-known nice tools and features in .NET together and come up with a workable solution. Because there is too much to cover in one article, we will mainly concentrate on business and persistence layers of N-Tier architecture in our sample solution, but will still briefly touch other layers too. In order to understand better this article, we suggest you to read first our previous article on the basics of N-Tier architecture here. As our previous article, this article is also based on the assumption that a team has a full control over all layers of the N-Tier architecture.

Using the MediaPlayer in WPF

In this article I am explaining how to use the MediaPlayer class in a WPF application. This is a relatively short article because I am describing only how to draw a MediaPlayer on a visual surface. To demonstrate this, I have created a demo application using Visual C# 2010 Express Edition.

There are two commonly used approaches to play media in a WPF application. One is using the MediaElementcontrol and the other is using the MediaPlayer class.

Using the MediaElement is a simple and straightforward approach. The MediaElement control has a Graphical User Interface and can be added using either XAML code or code-behind code. It provides playback and control capabilities using Play, Pause and Stop methods. The media file to be played is specified using the Source property of theMediaElement control.
