Below given some information about fav Icon
What Is FavIcon? ? FavIcon is nothing but small image which appears top left along with the application address bar title.Standard size specification for favicon.ico is 16 by 16 pixel. Please see below attached figure.
How It Works ? ? Usually we add our FavIcon.ico image in the route solution folder and automatically application picks it while running. But most of the time we might have to use below both link reference.
<link rel="icon" href="favicon.ico" type="image/ico"/>
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon"/>
Some browser expect one (rel="icon") Some other browser expect other rel="shortcut icon"
? Type=”image/x-icon” OR Type=”image/ico”: once expect exact ico image and one expect any image even formatted from .jpg or .pn ..etc.
? We have to use above two tags to the common pages like – Master page , Main frame which is getting used in all the pages
