I use visual studio 2008 to work on the web application. I don't have IIS on my vista, the problem is I am using authentication form mode in the web.config, now I want to exclude the registration page so I added the location tag ... but now if I navigate to the registration page, I am getting the error allowDefinition="MachineToApplication" .. I don't have IIS to look at the virtual directory, I only run my project via VS2008, what can I to do fix this?
