Build effective ASP.NET 2 web applications using Visual Studio 2005.

This course will provides you with the necessary skills and techniques to design and write web applications using ASP.NET 2.0, Microsoft's framework for building scalable, robust and secure Web applications.

You will gain in-depth technical knowledge of ASP.NET and its related technologies and obtain practical insights into developing enterprise-scale, data-driven Web applications. This will lead to an appreciation of the "plumbing" that is supplied by ASP.NET and Visual Studio 2005, leading to significant increases in your productivity.

Throughout the course you will be building a fully functional ASP.NET 2.0 web solution, using best practices including writing secure code to protect against potential malicious attacks. Instructions and solutions are provided in both C# 2.0 and Visual Basic 2005, enabling you to work with your choice of language.

Audience

Developers who want to create real-world Internet and Intranet applications using Microsoft ASP.NET 2.0. This course is also suitable for developers moving from Visual Basic or ASP.

Existing ASP.NET 1.x developers should attend the Upgrade Skills to ASP.NET 2.0 course.

Prerequisites

Delegates should have basic knowledge of HTML and web page creation. These skills can be obtained by attending QA's Building an Effective Web Site course.
