WPF Performance Improvements

.NET 3.5 SP1 includes several significant performance optimizations and improvements to WPF.  Some of the specific graphics improvements include:

Smoother animations

Hardware accelerated rendering of Blur and DropShadow Bitmap Effects

Text Rendering speed improvements - especially with VisualBrish and 3D scenes

2D graphics improvements - especially with z-index scenarios

A new WriteableBitmap class that enables real-time and tear-free bitmap updates.  This enables custom "paint"-style applications, data visualizations, charts and graphs that optionally bypass the default WPF 2D graphics APIs.

Layered window performance improvements

SP1 also adds support for better data scalability in WPF.  The ListView, ListBox and TreeView controls now support "item container recycling" and "virtualization" support which allows you to easily achieve a 40% performance improvement with scrolling scenarios.  These controls also now optionally support a "deferred scrolling" feature which allows you to avoid scrolling in real time and instead wait until a user releases the scroll thumb (the default scrolling mode in Outlook). This can be useful when scrolling over very large data sets quickly.

Title: Not seeing Classic ASP Intellisense

I'm not seeing the intellisense for classic asp even in .asp pages. Is there a setting or library that you have to reference for this to work?

Well now that the vs20008 sp1 rtm is out, I am having the same issue Tim mentions. Yes, I get my .asp color coding and intellisense back but only for .asp files. In VS 2005 all I had to do was to set the file assocition to web Editor for .inc file to make this work. Unfortunately this does not work in vs2008 sp1. What is the workaround?

Great so as long as we use .ASP pages and put VBscript at the top of each page it works. Not particularly useful though if you have one asp page including lots of .inc files that has all the code that you change on a day to day basis. At least in 2005 the highlighting worked in the .inc files. Now its comlpetely useless.

Is there no way to say all ".inc" files are ASP/VBScript pages?
