C# xaml解析器未检测到我的转换器

与许多其他解析器一样，xaml解析器决定不检测我的IvalueConverter对象。首先，转换器：

using System;
using System.Windows.Data;
namespace Chess_Piece_Viewer.Helpers
{
public class DebugConverter : IValueConverter
{

    public Object Convert(Object value, Type targetType, Object parameter, System.Globalization.CultureInfo culture)
    {

        //set a breakpoint here
        return value;
    }

    public Object ConvertBack(Object value, Type targetType, Object parameter, System.Globalization.CultureInfo culture)
    {

        //set a breakpoint here
        return value;
    }

}

}

现在视图（请注意DebugConverter对象在Visual Studio中加了下划线，因为解析器无法检测到它，这是我的问题：
