I'm trying to set up a simple Bing Map web part that would pull list items to populate the map with pins. I was able to get a static data pull (created objects to populate pins), but once I tacked in the Client OM code, it stopped working. It didn't fail, but it didn't work and I couldn't connect the debugger.

I'm completely stumped as to what's going wrong. Here are my questions:

  1. Why can I not get the debugger to recognize my breakpoints when connected to all the iexplorer.exe instances?
  2. Why does my code not run? I don't see the dll deployed anywhere, so should that be deployed and to where?
  3. Is there a way to automatically have the SharePoint project deploy to clientbin? The only way I've found to get this to work is by manually dragging the xap into the mapped clientbin folder in the SP project.
    1. List item

Here's my XAML markup:

<UserControl x:Class="FH.SharePoint.Offices.POIMap.MainPage"
d:DesignHeight="300" d:DesignWidth="400" Loaded="UserControl_Loaded">

<Grid x:Name="LayoutRoot" Background="White">
    <m:Map CredentialsProvider="APIKey" x:Name="NearbyPOIMap" Mode="Road">
        <m:MapLayer Name="uxErrorLayer" Visibility="Collapsed">
            <Canvas m:MapLayer.Position="0,0" Background="Blue" Width="340" Height="30">
                <TextBlock FontWeight="Bold" Foreground="Red" Text="Error retreiving offices locations from the server" TextWrapping="Wrap" Margin="5" MaxWidth="100" MaxHeight="40"></TextBlock>


Here's the code I have. I commented out the section that worked in the test VS Web App I created. Even that didn't work once I deployed to SharePoint.

This link might help you out:



Vardhaman's link helped me figure out what was going on.

The reason I wasn't able to connect the debugger is because of the way I was getting the XAP into the SharePoint project. I was manually grabbing it and dropping it into the SP project. On build, it would rebuild the Silverlight project as well, so it wouldn't be the same version number. I was able to get the SP project to reference the Silverlight project properly (although it's going to the _catalogs/masterpage library instead of clientbin, but that's fine for my situation).
