How to use IIS Developer Express from Visual Studio?

IIS developer express is a new web server from Microsoft for ASP.NET developers for non production use. The new developer edition of IIS comes with a lot of cool features from IIS and Visual Studio's built-in web server combined in to one software, making it a better tool for developers.
As of now, the IIS developer express is not a separate download and there is no separate installer. It need to be installed through the WebMatrix software install. WebMatrix can be installed using an installer called "Web Platform Installer", which can be used to install a bunch of web development tools from Microsoft and third parties.

On 7 July 2010, Microsoft announced Web PI 3 along with WebMatrix beta. WebMatrix is an integrated web application development tool which include a developer version of IIS called 'IIS Developer Express'.
The Web PI 3 installer can install a large number of web application development tools, including:

WebMatrix (which includes IIS Developer Express)

SQL Server Compact

SEO tools

Third party web application tools like DotNetNuke, Umbraco, WordPress and Joomla!

SQL Server Express
and many more.

The components included in Web PI installer are dynamically loaded from Microsoft web services, so this list can change and add more stuff any time.
You can download WebMatrix Beta installer (Web PI 3 beta) from here: http://www.microsoft.com/web/webmatrix/download/

As of now, there is no Visual Studio integration for IIS Express. If you like to use IIS Developer Express from Visual Studio, your options are limited to:
1. Open WebMatrix, start IIS Express and then run your Visual Studio website against the site hosted in IIS Express.
2. Launch IIS Express from command prompt.

Manage IIS Express from system tray:
There is an IIS Express System Tray utiltiy (iisexpresstray.exe) which places an icon in the system tray and allow you to manage the sites hosted in IIS Express.
This utility allows you to view the list of all sites hosted in IIS Express and you can start/stop the sites from here.
When IIS developer express is started, by default the system tray utility also starts, unless you disable it explicitly.
One of the problems I found with this system tray utility is, it always starts in the bottom right corner of my screen, with only a small portion of it in the visible area of the screen. Rest of the screen is hidden outside the visible boundary of the screen. I had no ways to drag this screen to a visible area. The drag option simply does not work since the screen does not have a draggable title bar. My only option was to expand the size of the window so that most part of the content is visible.
