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.
Getting started with ASP.NET 2.0 ASP.NET 2005 is part of a whole suite of applications and user interfaces that are packed under the banner of Visual Studio.NET 2005. Code named as Whidbey, the entire package is still being tested and the final version is slotted to be released late this year. The suite includes the .NET Framework; user interfaces like Windows forms, ASP.NET and Compact framework; Official languages like C#, J# and Visual Basic.NET; Integrated Development Environment (IDE) like Visual Studio.NET. Scope of the tutorial This tutorial series proposes to cover in detail the new features introduced in ASP.NET; improvements…
.NET Framework Fundamentals Understanding the .NET Framework .NET framework is a Windows Component that supports the building and running of windows applications and XML Web services. The purpose of the component is to provide the user with a consistent object oriented programming environment whether the code is stored locally or remotely. It aims to minimize software deployment and versioning conflicts and also promote safe execution of code including codes executed by trusted third parties. It is directed towards eliminating performance problems of scripted or interpreted environments. The effort is to make developer experience consistent across a variety of applications and…
.NET Framework Tools In order to facilitate ease of development and deployment of applications, the .NET framework provides the user with a number of tools.
