I want to place a <EPiServer:LogGenerator ID ...> tag in my masterpage but I get the keep getting the error: "Element 'LogGenerator' is not a know element ...". It should be in the assembly EPiServer.Web.WebControls, whose TagPrefix is registered in web.config (I've also tried to registered it in the top of the page manually but it didn't work). The project I am working with is created using the Visual Studio template EPiServer Project 5.1.422.4.

If I choose to install an EPiServer website using the EPiServer CMS Manager and the PublicTemplates, then it works. I can't see what is the difference between them regarding the LogGenerator. What am i missing in the first clean project?
