When ASP.NET hit the street a couple of years ago, it was a
real eye-opener. Microsoft''''s tool for creating dynamic,
server side web applications introduced Web Forms, a feature
with the same rapid drag and drop convenience enjoyed by
Visual Basic developers, along with a method for creating
XML-based web services. ASP.NET was more than an upgrade of
Active Server Pages it was a quantum leap ahead.
Now Microsoft has a new version of ASP.NET as part of its
upcoming next generation release of the Visual Studio .NET
development platform. ASP.NET 2.0 is already available in
beta release, and web developers are anxious to get a good
look at it. That''''s exactly what our new Developer''''s Notebook
allows you to do.
More than just an introduction to ASP.NET 2.0, this
practical guide acquaints you with all of the new features
through nearly 50 hands-on projects. Each one places
emphasis on changes in the new release that can increase
productivity, simplify programming tasks, and help you add
functionality to your applications. For example, ASP.NET 2.0
includes master pages, themes, and skins so you can build
applications with a consistent page layout and design. Other
changes allow for the automatic creation of web pages for
use on mobile devices, while wizards and controls allow you
to perform frequent tasks (like data access) without having
to write a single line of code.
ASP.NET 2.0: A Developer''''s Notebook
also includes suggestions for further experimentation, links
to on-line documentation, and practical notes and warnings
from the author regarding changes to the new version.
The new Developer''''s Notebooks series from O''''Reilly offers an
in-depth first look at important new tools for software
developers. Emphasizing example over explanation and
practice over theory, they focus on learning by doing you''''ll
get the goods straight from the masters, in an informal and
code-intensive style. If you want to get up to speed on
ASP.NET 2.0 before its official release, this all lab, no
lecture book will get you there.
Chapter 6. Performance
ASP.NET 2.0 includes new featuresthat enhance the
performance of your web applications. For example, in ASP.NET 1.x,
pages are dynamically compiled and cached the first time a user loads
a page. As a result, an ASP.NET 1.x web application is typically
slower the first time it is loaded. In ASP.NET 2.0, you can now
precompile your site so that it's already compiled
when the first user pays a visit.Note: You can now make changes to your ASP.NET 2.0 web
application and it will recompile on the fly.
In ASP.NET 1.x, all code-behinds are compiled into an assembly and
stored in the /bin directory of the application,
while the web pages (.aspx) are compiled on
demand. And so any changes made to the .aspx
page will automatically be updated, whereas changes to the
code-behind of the page will not be recompiled until you explicitly
request it.In ASP.NET 2.0, you can use dynamic runtime compilation so that any
changes made to either the .aspx or
.vb (or .cs) files will
automatically trigger a recompilation of the page.
