Create a spotlight control

Hello,
I'm new to WPF(coming from winform), and I'm trying to build a "spotlight control"(because I want to reuse it in other applications). When I try to compile I get BC30002 SpotLight:LedControl is not defined, but it actually exist.
This is the xaml code:

Code:

        <local:LedControl x:Name="btnGreen"  OnColor="Yellow" IsChecked="false" Height="36" OffColor="#FF9BA40C"  Width="36"  Grid.Column="1" Click="btnGreen_Click"/>

    </Grid>
</UserControl>

And this is the code behind:

Code:

---

Imports LedControl
Public Class SpotLight
    Private Sub btnRed_Click(sender As Object, e As RoutedEventArgs)
        If btnRed.cheched = False Then
            btnRed.cheched = True
            btnGreen.checked = False
            btnYellow.checked = False
        End If
    End Sub


    Private Sub btnGreen_Click(sender As Object, e As RoutedEventArgs)
        If btnGreen.cheched = False Then
            btnRed.cheched = False
            btnGreen.checked = True
            btnYellow.checked = False
        End If
    End Sub

    Private Sub btnYellow_Click(sender As Object, e As RoutedEventArgs)
        If btnYellow.cheched = False Then
            btnRed.cheched = False
            btnGreen.checked = False
            btnYellow.checked = True
        End If
    End Sub


End Class
Public Class LedControl
    Inherits CheckBox

    Shared Sub New()
        DefaultStyleKeyProperty.OverrideMetadata(GetType(LedControl), New FrameworkPropertyMetadata(GetType(LedControl)))
    End Sub

    Public Shared ReadOnly OnColorProperty As DependencyProperty = DependencyProperty.Register("OnColor", GetType(Brush), GetType(LedControl), New PropertyMetadata(Brushes.Green))

    Public Property OnColor As Brush
        Get
            Return CType(GetValue(OnColorProperty), Brush)
        End Get
        Set(ByVal value As Brush)
            SetValue(OnColorProperty, value)
        End Set
    End Property

    Public Shared ReadOnly OffColorProperty As DependencyProperty = DependencyProperty.Register("OffColor", GetType(Brush), GetType(LedControl), New PropertyMetadata(Brushes.Red))

    Public Property OffColor As Brush
        Get
            Return CType(GetValue(OffColorProperty), Brush)
        End Get
        Set(ByVal value As Brush)
            SetValue(OffColorProperty, value)
        End Set
    End Property
End Class

What am I missing?
