I would like to know how is it possible to add these custom tags dynamically to my sitemap.xml?I am using mvcsitemapprovider
well, I could not use the mvcsitemapprovider to achieve my goal yet, but I made this temporary solution and I am trying to make nuget package from it or add it as a feature to the mvcsitemapprovider package, here is the code I added to an ContentResult in a controller and I changed my routeConfig to call this method when the url is look like this "/videoSiteMap.xml" :
I replaced utf-16 with utf-8 while returning my xml data because I could not find an easier way to change XmlWriter's result (by default it always returns a utf-16 format)
I hope it help the others, I will be glad if someone help me to make it a nuget package or something :D
