Migrating from Bing Maps Silverlight CTP to Production version

With the official release of the Bing Maps Silverlight control there has been some changes from the CTP version. This article will address the required changes needed to migrate from the CTP version to the production version.

The first change is that the control now requires Silverlight 3. So if you are still using Silverlight 2 you will have to upgrade. You can get the required files to upgrade to Silverlight 3 here: http://silverlight.net/getstarted/

With the production version being released you are now required to authenticate the map. In the CTP version Microsoft took care of the authentication. The Silverlight control does not use tokens like the AJAX control; you can now use an application key. This removes the need to retrieve a client token when you load your map which means faster loading times. To get a key you first need an account. You can get an account here: https://www.bingmapsportal.com. After creating an account you can sign in using your Windows Live ID. Once signed in you can create up to 5 keys by clicking on the Create or view keys on the left side panel. To create a new key, enter the name of your application and the URL which corresponds to the website where the key will be used. Then click the Create key button. Once the key is created you can copy it and use it in your code. There are two ways to add this application id to your code. The first is to set the ApplicationId property of an ApplicationIdCredentialsProvider object and then use this object to set the CredentialsProvider property of the MapBase object. Alternatively you can add the application key to the XAML like so:

<UserControl x:Class="SilverlightApplication1.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation&quot; xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Width="1024" Height="768">
       <Grid x:Name="LayoutRoot" Background="White">
             <m:Map x:Name="myMap" CredentialsProvider="Your key" Mode="Road"/>

You will need to update your Virtual Earth map control assembly reference. The new assemblies have been renamed as well. You will need to replace Microsoft.VirtualEarth.MapControl.dll with both Microsoft.Maps.MapControl.dll and Microsoft.Maps.MapControl.Common.dll.

With the change in assemblies the namespaces have also changed. Here is a mapping of the new namespaces:
