Programming Scalable Web Applications with .NET and ASP.NET AJAX: Hands-On
You Will Learn How To
- Create scalable Web applications using Visual Studio, ASP.NET and AJAX
- Leverage ADO.NET and LINQ to build a data layer, custom business entities and typed DataSets
- Program a stateless business layer with transactional .NET components
- Create a more responsive UI using ASP.NET AJAX, WCF Web services and the AJAX toolkit
- Secure Web applications using forms authentication and the membership API
- Employ distributed sessions to balance performance and scalability in a Web farm
Course Benefits
In today's Internet-dependent world, organisations need sophisticated and robust Web applications to meet their client's needs. In this course, you create a scalable multitier Web site that is both secure and reliable using Visual Studio 2008 and .NET. You learn how to use ADO.NET and LINQ, present Web content via AJAX and ASP.NET, call WCF services from ASP.NET AJAX and utilise message queuing for asynchronous distributed programming.
Who Should Attend
Those programming robust Web applications. Programming experience at the level of Course 503, "Visual Basic Programming for .NET", or Course 419, "C# Programming", and Web development experience are assumed. ASP.NET experience is helpful.
