Hi expert,

I have an error when running files as below:

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

<siteMap defaultProvider="AspXmlSiteMapProvider" enabled="true">
The virtual directory has been set up and the microsoft.net framework 3.5 SP1 has been installed.
how to fix it? Appreciate it!!

Hi there,

You typically get this error when you open the parent folder of the folder that contains the site. So, if your source is here:

C:\MySites\Chapter6

and then open C:\MySites as a web site in Visual Studio and browse to http://localhost:123/Chapter6 you get this error. Instead, you need to open C:\MySites\Chapter6 as a web site in Visual Studio and browse to http://localhost:123/

Hope this helps,

Imar
