What if I didn't make use of a master page, where will i put the code? I tried inserting it right after the title tag of my default.aspx (this is the only place where I had seen that the code link rel is accepted), yet no icon appeared on the left of my site address. I inserted a .ico file in the images directory anyway.
i have tried it creating a new project and it worked without any problems. Is your default page in the root folder of your application? The href must be relative to your document. I can't think of any other problem for it not to work.
