Earlier today the IIS Express team released the IIS 8.0 Express Beta, and there are some great new features in this release! Here are just a few of the highlights:

64-bit Support
IIS 8.0 Express now fully supports 64-bit application development. When you install IIS Express on a 64-bit system, you actually get both 32-bit and 64-bit versions of IIS 8.0 Express installed, which allows you to use the version that matches your project's needs.
Customizable Home Directory
The default home directory for IIS Express is "%UserProfile%\Documents\IISExpress", but with IIS 8.0 Express you can start the iisexpress.exe process with the "/userhome" parameter to specify the home directory for your projects; this makes it easier for you to use IIS 8.0 Express with multiple development applications.
AppCmd Support for Multiple ApplicationHost.config Files
As a complement to allowing users to customize their IIS Express home directory, IIS 8.0 Express contains a new version of AppCmd.exe that supports a new "/AppHostConfig" parameter, which makes it possible to use AppCmd.exe to edit multiple ApplicationHost.config files. By default AppCmd.exe for IIS 7 or IIS 7.5 Express will only edit the ApplicationHost.config file in your "%WinDir%\System32\InetSrv\Config" or "%UserProfile%\Documents\IISExpress" folder, but the AppCmd.exe command-line utility that ships with IIS 8.0 Express allows you to edit ApplicationHost.config files anywhere on your system.

  • "%UserProfile%\Documents is not for you my friend. I will thank you to keep your stuff out of my documents folder. I'd like to use it for documents, you know?

    Try "%UserProfile%\IISExpress next time.

  • I gave up on feeling like I had any control over %UserProfile%\Documents years ago. I just abandoned it and keep real documents somewhere completely different.

    Anyway, I have a question - given that Visual Studio 2010 is x86, how can I use IIS Express to debug web applications that need to run as x64? Do I need to start IIS Express outside of Visual Studio and then attach to the process? If that's the case then I might as well just use standard IIS.

  • I agree, how is the content of IISExpress like a Word Document or Excel Spreadsheet to justify being in my Documents folder?

  • Well, we ARE talking about the same company that puts pictures/video/music libraries on Data Center Edition as well... So no surprises that they think that My Documents is where this stuff goes.

    So, to echo the feedback: I agree - it doesn't belong there - or at least let me chose that. (No, really.)

    OTHERWISE, complaints/feedback aside: this is stellar. Great work.
