Why can’t I debug from Visual Studio 2005 after installing IE8?

I’ve just installed IE8 (final) and restarted. I can no longer debug Web Application Projects using Visual Studio 2005 on Windows Server 2003 Enterprise R2. I get the message “Internet Explorer cannot display the webpage” and then WebDev.WebServer.exe quits with no visible error message and nothing in the Event Viewer.

How to Enable JavaScript file API in IE8

I have developed a web application in asp.net, there is a page in this project which user should choose a file in picture format (jpeg, jpg, bmp,…) and I want to preview image in the page but I don’t want to post file to server I want to handle it in client i have done it with java scripts functions via file API but it only works in IE9 but most of the costumers use IE8 the reason is that IE8 doesn’t support file API is there any way to make IE8 upgrade or some patches in code behind I mean that check if the browser is IE and not support file API call a function which upgrades IE8 to IE9 automatically.
