Iis – Sample ASP.NET web application for IIS testing

I have the same problem when try publishing SL App using VS2010 although there is no prob before with .NET 3.5SP1 and VS2008.

So try run this (%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i) as described here forums.iis.net/t/1149449.aspx and here www.gotknowhow.com/articles/fix-bad-module-managedpipelinehandler-in-iis7 and It works now. So the problem is ASp>NET 4.0 has not properly installed, huuu... :)

For hosting it for external access, IIS the way to go (99% of people do that on a Windows computer). You can add it in Windows 7 from Programs and Features -> Turn Windows Features on or off -> Internet Information Services.

Once you install it then edit your Default Web Site and point it to your project root folder. Now browse to http://localhost or http://computer_name_or_ip.
