Outlook AddIn context menu does not recognize MailItem

Question

Hi, 
  I just start program for Outlook in Visual Studio. I plan to start from creating right click menu in Outlook Home email panel.  I got the example code from
Context Menu for a Mail Item of
Extending the User Interface in Outlook 2010. When I test it, I select a email in Outlook, right click my context menu item, it does not think it's a MailItem. What's wrong in my code? How I can debug it? Do you know any good book/blog/example/tutorial? 
  Here is the code:     
<contextMenus>
<contextMenu idMso="ContextMenuMailItem">
<button id="MyContextMenuMailItem"
label="OAIContextMenuMailItem"
onAction="OnMyContextMenu_Click"/>
</contextMenu>
</contextMenus>
public void OnMyContextMenu_Click(Office.IRibbonControl control)
System.Windows.Forms.MessageBox.Show("Your Context Menu Works!");
if (control.Context is Outlook.Explorer)
Outlook.Explorer explorer = control.Context as Outlook.Explorer;
Outlook.Selection selection = explorer.Selection;
if (selection.Count == 1)
if (selection[1] is Outlook.MailItem)
Outlook.MailItem oMail = selection[1] as Outlook.MailItem;
//return oMail.Sent;
System.Windows.Forms.MessageBox.Show("Sent");
else
System.Windows.Forms.MessageBox.Show("Not MailItem");
else
System.Windows.Forms.MessageBox.Show("Multiple selection");
else if (control.Context is Outlook.Inspector)
Outlook.Inspector oInsp = control.Context as Outlook.Inspector;
if (oInsp.CurrentItem is Outlook.MailItem)
Outlook.MailItem oMail = oInsp.CurrentItem as Outlook.MailItem;
//return oMail.Sent;
System.Windows.Forms.MessageBox.Show("Sent at Inspector");
else
System.Windows.Forms.MessageBox.Show("Not MailItem at Inspector");
else
System.Windows.Forms.MessageBox.Show("not a Explorer/Inspector");
Thank you so much
Wes

Can you try to retrieve the Class property using reflection?
