Should be simple as pie. Using Expression Blend 2 September Preview the icon will display properly in the MenuItem in the design mode but when I run the application the icon disappears. What am I missing? Thanks. Here's the code: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Window1" x:Name="wndMain" Title="Window1" Width="640" Height="480"> <Grid x:Name="gridRoot"> <Menu HorizontalAlignment="Stretch" VerticalAlignment="Top" x:Name="menuMain"> <MenuItem x:Name="mnuiFile" Header="_File"> <MenuItem x:Name="mnuiFile_Close" Header="_Close"> <MenuItem.Icon> <Image Source="graphics/error.ico" Height="15" Width="15" Stretch="Fill"/> </MenuItem.Icon> </MenuItem> </MenuItem> </Menu> </Grid> </Window>
