using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
using System.Windows.Media;
using System.Windows.Controls;
using System.Windows;

using Microsoft.Windows.Design;
using Microsoft.Windows.Design.Features;
using Microsoft.Windows.Design.Metadata;

namespace CustomControlLibrary.Design
    public class ButtonWithDesignTime : Button

    // Container for any general design-time metadata to initialize. 
    // Designers look for a type in the design-time assembly that  
    // implements IRegisterMetadata. If found, designers instantiate  
    // this class and call its Register() method automatically. 
    internal class Metadata : IRegisterMetadata
        // Called by the designer to register any design-time metadata. 
        public void Register()
            AttributeTableBuilder builder = new AttributeTableBuilder();

                new ToolboxBrowsableAttribute(true));
