Differences between my code and demo code

Hi guys,

Maybe I've been on holiday too long, but I just downloaded the code at:

http://support.microsoft.com/kb/910442

And am finding that my own class library project has one tiny difference that seems to be stopping it from working...
In the line in the assemblyinfo.cs:

[assembly: System.Web.UI.WebResource("WebControls.Stylesheet.css", "text/css")]

In visual studio 'WebResource' (in the line above) does not highlight in blue, whereas in the demo code project, it does.

I take it to mean that when the WebResource.axd not found error occurs, this is because the runtime location of that code is incorrect, hence VS not indicating to me that it knows where it is.

Unfortunately, I cannot see the difference between the two projects and have even compared files in beyond compare. No dice.

Could someone tell me what is supposed to be going on in the AssemblyInfo.cs file and how I can get references to my files in there properly, please ...
