[issue]
In Windows Vista & Longhorn Server Beta 2, %windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe is still present but with different functionality. Basic behaviors work, but it is highly recommended that you use alternative tools.
[workarounds]
You can still use aspnet_regiis, but not all the command line switches work. As such, you should:
- Use the Control Panel "Windows Features" option to install/remove ASP.NET
- Use the IIS7 management control (%windir%\system32\inetsrv\inetmgr.exe) or the new AppCmd tool to configure ASP.NET applications (%windir%\system32\inetsrv\appcmd.exe)
