I've downloaded the most recent version and started a new project to play with the controls. I've added a reference to the DLL and added it to my toolbox.
After dragging the DayPilotScheduler (or DayPilotCalendar) into the webform, intellisense tells me that they are not a known element.
Rebuilding the project changes nothing, and the build is successful--no errors. The intellisense error mentions not having a web.config, but there is one.
Rendering the page results in a similar error: Unknown server tag 'DayPilot:DayPilotScheduler'.
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34280
Here is the code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="daypilot.WebForm1" %>
<%@ Register assembly="DayPilot" namespace="DayPilot.Web.Ui" tagprefix="DayPilot" %>
<form id="form1" runat="server">
My .net and Visual Studio experience is slim so I must be missing something somewhere. There is nothing but normal template in the code-behind.
