Category: ASP.NET 2.0

Microsoft’s ASP:NET 2.0 is an upgrade to the ASP.NET 2005 package of applications and user interfaces that fall under the umbrella of Visual Studio.Net 2005. The suite of applications in the .NET framework that the programmer should be familiar with includes Windows forms user interfaces, Compact and ASP.NET framework, C#, j#, VB.NET (Visual Basic) and developer tools such as Integrated Development Environment (IDE).

To successfully pursue a career in IT professionally, programmers and developers must be well versed in their knowledge of the .NET framework, “the Windows Component that supports the building and running of windows applications and XML Web services”. The component provides a consistent object-oriented programming environment for the user, when stored both locally and remotely. This allows for the scripted or interpreted environment to perform well within an assortment of .NET applications and platforms.

Tutorials and training information about ASP.NET 2.0 includes Application Development in Visual Studio.NET, in-depth examination of SQL Server 2005 framework support and a detailed section on Web Pages, Layout and Controls. Beginner, Intermediate and Advanced users can benefit from the ASP.NET 2.0 tutorials and training articles which are written from both developer and the user point of view.
