WPF Namespace Struggles

Would appreciate help to get this code to work.

I'm using VisualStudio 2012, using WPF with VB.NET.

I have a namespace named MyNameSpace. It's defined at the solution level

It has a number of projects within it.

I'm trying to get a ValueConverter to be recognized so that I can use it.

Purpose is to convert a value of type DateTime, which includes date and time, to simply MM/dd/yyyy

Below is code for a window in one project, followed by the window's code-behind.

Thank you very much.

MyWin.XAML:

<Window x:Class="MyWin"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MyWin" Height="300" Width="300"
    xmlns:local="clr-namespace:MyNameSpace">
    <Window.Resources>
        <!-- ERROR ON NEXT LINE: The name DateConverter does not exist in the namespace-->
        <local:DateConvertor x:Key="MyDateConverter"/>
    </Window.Resources>
    <Grid>
        <DataGrid>
            <DataGrid.Columns>
                <DataGridTemplateColumn  Width="auto" Header="Do By">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Margin="4" Text="{Binding Path=DoByDate}" />
                            <!-- Cannot use the converter to show MM/dd/yyyy.-->
<!--                        <TextBlock Margin="4" Text="{Binding Path=DoByDate, Converter={StaticResource DateConvertor}}" /> -->
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                    <DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate>
                            <DatePicker SelectedDate="{Binding Path=DoByDate, Mode=TwoWay}" />
                        </DataTemplate>
                    </DataGridTemplateColumn.CellEditingTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>
