When you first run VS 2010 it prompts you to select an IDE profile to use.  The profile you select will configure how tool windows are displayed/docked in the IDE by default and set the default keyboard shortcuts.  You can then customize any of these settings by using the Tools->Options menu within the IDE and then override/change them.  You can also later reset your profile and pick a different one by choosing the Tools->Import and Export Settings menu command.

One of the things you’ll notice when you run VS 2010 Beta2 for the first time is the inclusion of two “Web Development” profiles in the list of options:

The first “Web Development” profile option is an evolution of the existing web development profile option from VS 2008 (with some nice improvements that help improve screen real estate usage with VS 2010).  It also allows you to take advantage of all the great WYSIWYG HTML and ASP.NET Page designer improvements we’ve done with the VS 2010 release (I’ll cover these in more detail in later blog posts in this series).

The second “Web Development (Code Optimized)” profile option is a new profile we are introducing with VS 2010 that is optimized for web developers who do not want to use a WYSIWYG designer when doing their web development, and who prefer a “source only” editing experience when working on pages.  This IDE profile option hides the WYWISYG page designer tabs, and configures a default IDE layout that maximizes the amount of code that is displayed on the screen (with a minimum of toolbars and tool windows).  It still provides a full intellisense/debugging and source editor experience for pages.
