RE: ASP.NET Membership

Hello Marshall,

I suspect this problem is related to the X64 platform you used. There are
similar issue reported on X64 and the cause is due to missing ASP.NET
registry keys. The reason these were missing was because we had installed
ASP.NET after the IIS metabase setting Enable32bitAppOnWin64 had already
been set to 1. Because IIS had already been switched to 32-bit mode, the
ASP.NET installation did not create the ASP.NET registry keys in the
"64-bit" registry, only in the "32-bit" (redirected) registry. This can be
fixed by running following commands in a command prompt :

1. cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs set
w3svc/AppPools/Enable32bitAppOnWin64 0
2. %windir%\microsoft.net\framework64\v2.0.50727\aspnet_regiis.exe ¨C i
3. cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs set
w3svc/AppPools/Enable32bitAppOnWin64 1
4. %windir%\microsoft.net\framework\v2.0.50727\aspnet_regiis.exe ¨C i

What this does is switch IIS to 64-bit mode, run the installation of 64-bit
ASP.NET, switch back to 32-bit mode and then re-install 32-bit ASP.NET.
Doing this causes the right registry keys to be created. This allows Visual
Studio to correctly locate the path to WebDev.WebServer.exe so the Visual
Studio dev web server can be launched.
