With a developer account, you get full access to the APIs and staging environment, which you can use to build applications for trial, demonstration, and proof-of-concept purposes.

Overview

Microsoft Dynamics CRM Account entity already has longitude and latitude parameters for address. But mostly organizations don't use those parameters. This provides FindAddress service to resolve addresses and returns longitude and latitude parameter as shown in the code snippet below. 

Find Address Longitude and Latitude FindServiceSoap FindService = new FindServiceSoap ();
FindService.Credentials = new NetworkCredential("", "");
FindService.PreAuthenticate = true;MyAddress mAddress = new MyAddress(); mAddress = (MyAddress)addresses[i];FindAddressSpecification spec = new FindAddressSpecification();
spec.InputAddress = new Address();
spec.InputAddress.AddressLine = mAddress.Line1;
spec.InputAddress.CountryRegion = mAddress.Country;
spec.InputAddress.Subdivision = mAddress.StateProvince;
spec.InputAddress.PrimaryCity = mAddress.City;
spec.InputAddress.PostalCode = mAddress.Postalcode;
spec.DataSourceName = "MapPoint.NA";
FindResults results = FindService.FindAddress(spec); Populating Location and Pushpin Array Location and pushpins objects require longitude and latitude values for address. Following code is used to populate Location and Pushpin objects of MapPoint API. 

Location[] myLocation = new Location[addresses.Count];myLocation[i] = new Location();
myLocation[i].LatLong = new LatLong();
myLocation[i].LatLong = results.Results[0].FoundLocation.LatLong; Pushpin[] pushpins = new Pushpin [addresses.Count]; pushpins[i] = new Pushpin();
pushpins[i].PinID = "pin0″;
pushpins[i].IconName = "0″;
pushpins[i].Label = mAddress.Name;
pushpins[i].IconDataSource = "MapPoint.Icons";
pushpins[i].LatLong = results.Results[0].FoundLocation.LatLong;There is no simple way to provide hyperlink at Pushpins, although Pushpin label and icon can be set to custom settings.  Getting image and automatic zoom based on the geography covered by the addresses

Map Point Web Service provides Render Service API to automatic zoom based on the geography covered by addresses. Here is the code snippet to do this: //Call MapPoint Render Web Service RenderServiceSoap RenderService = new RenderServiceSoap();
RenderService.Credentials = new NetworkCredential("", "");
MapViewRepresentations mvRep = RenderService.GetBestMapView(myLocation,"MapPoint.NA");mviews[0] = new ViewByBoundingRectangle();
mviews[0] = mvRep.ByBoundingRectangle;MapSpecification mspec = new MapSpecification();
mspec.Options = moptions;
mspec.Views = mviews;
mspec.Pushpins = pushpins;
mspec.DataSourceName = "MapPoint.NA";MapImage[] image = RenderService.GetMap(mspec); So the final image can be displayed in some ASP.NET page to show in Microsoft Dynamics CRM. Please find below my integration of MapPoint web service with MSCRM. One can select Accounts to be plotted on MapPoint and click Show Accounts Map Button

at Account Entity grid toolbar.  All selected accounts will be plotted on the MapPoint in a new web dialog with Invalid addresses at the bottom.    
 Here is the final Image generated in Web Dialog:
