Let's create our sample application using Silverlight. We will create a Silverlight web resource using Bing Map Silverlight SDK, to show all accounts related to the current CRM user. We will display a pushpin for the account. Once our sample application is ready, we will upload this web resource on a dashboard in Microsoft CRM 2011. Before creating our application, we need to customize the account entity form and need to add the OOB Latitude and Longitude fields in the account entity form, as shown in the following screenshot:

We need to make sure we fill the Latitude and Longitude fields for our account to see pushpins for these accounts.
