Building a Web 2.0 Portal with ASP.NET 3.5
If you think you're well versed in ASP.NET, think again.
This exceptional guide gives you a master class in site
building with ASP.NET 3.5 and other cutting-edge Microsoft
technologies. You learn how to develop rock-solid web portal
applications that can withstand millions of hits every day
while surviving scalability and security
pressures -- not
just for mass-consumer homepages, but also for dashboards
that deliver powerful content aggregation for enterprises.
Written by Omar AL Zabir, co-founder and CTO of Pageflakes,
Building a Web 2.0 Portal with ASP.NET 3.5 demonstrates how
to develop portals similar to My Yahoo!, iGoogle, and
Pageflakes using ASP.NET 3.5, ASP.NET AJAX, Windows Workflow
Foundation, LINQ and .NET 3.5. Through the course of the
book, AL Zabir builds an open source Ajax-enabled portal
prototype (available online at www.dropthings.com), and
walks you though the design and architectural challenges,
advanced Ajax concepts, performance optimization techniques,
and server-side scalability problems involved.
You learn how to:
Implement a highly decoupled architecture following the
popular n-tier, widget-based application model
Provide drag-and-drop functionality, and use ASP.NET 3.5 to
build the server-side part of the web layer
Use LINQ to build the data access layer, and Windows
Workflow Foundation to build the business layer as a
collection of workflows
Build client-side widgets using JavaScript for faster
performance and better caching
Get maximum performance out of the ASP.NET AJAX Framework
for faster, more dynamic, and scalable sites
Build a custom web service call handler to overcome
shortcomings in ASP.NET AJAX 1.0 for asynchronous,
transactional, cache-friendly web services
Overcome JavaScript performance problems, and help the user
interface load faster and be more responsive
Solve scalability and security problems as your site grows
from hundreds to millions of users
Deploy and run a high-volume production site while solving
software, hardware, hosting, and Internet infrastructure
problems
Building a Web 2.0 Portal with ASP.NET 3.5 also presents
real-world ASP.NET challenges that the author has solved in
building educational and enterprise portals, plus thirteen
production disasters common to web applications serving
millions of users. If you're ready to build state-of-the
art, high-volume web applications, this book has exactly
what you need.
