I am sorry to have to re-open this post. Mikhail or someone, could you give me some more pointers please? I am really flying blind with the aspnet_compiler. In this link is a screenshot of the console window. the line in question is:
aspnet_compiler -p c:\AccordionSiteMap\AccordionSiteMap.sln
Error 1003: The directory ... doesn't exist.
If there is reading that I should be dong about .sln's and .csproj's and such, then just point me to it. basically I downloaded one of these, and installed it. Now I want to swap out the version of AjaxControlToolkit for a more recent one and re-compile it.
If I need to figure out about virtual directories in IIS, then that will be more learning for me, never previously gone near IIS.
Many thanks,
