What’s New In The Updated ArcGIS API For Microsoft Silverlight/WPF

Earlier today the updated ArcGIS API for Microsoft Silverlight/WPF was made available for download from the ESRI Resource Centre for ArcGIS Server. Information about this can be found on my post here: http://geo.geek.nz/esri/…

A few people have been wondering what’s new or what has changed in this latest build. This information has just been published for build 1.0.0.209.

Resolved bugs:

• Resizing the map control continously will generate a large number of requests for dynamic layers.
• Map shows erroneous results when SnapToLevels is true and an explicit extent is set on the map.
• Map fails to show layers if SnapToLevels=true and contains only dynamic layers and/or failed tiled layers.
• Create a new template for controls in the Widgets assembly does not work in Microsoft Blend.
• When changing a graphic symbol on the fly, the element disappears until you pan or zoom.
• An internal MouseEnter event handler on the Map control always assigns focus to the map. The handler has been removed.
• Graphics layers cannot be used by themselves in a map.
• Large requests by tasks are failing. If a task creates a Web request with greater than 2048 characters in the URI, the task will use POST (instead of GET) to submit the request.
• Set the default Tolerance property value of the IdentifyParameters class to 2.
• Unable to change the Virtual Earth TileLayer Url property at runtime.
• Mouse wheel zoom speed in Google chrome is too fast when compared to other supported browsers.
• GPResultImageLayers are not returned in the correct spatial reference.

Updates\Enhancements:

• Breaking Change: The Draw class has been modified. It is no longer a FrameworkElement and should not be defined in XAML. Instead Draw is a simple lightweight class that can be instantiated and used in the code-behind. The Activate and Deactivate methods have been removed. Use the IsEnabled and DrawMode properties in their place. See the Draw Graphics or Spatial Query samples in the interactive SDK for an example.
• New OverviewMap and MagnifyingGlass controls in Widgets library.
• Layer definitions supported on ArcGISDynamicMapServiceLayer.
• New copyright text features added to the Map. Defined via the ILayerCopyright interface.
• The spatial reference of an Envelope used to define the extent of a Map must match the Map’s spatial reference.
• You can define an explicit spatial reference for the map upon initial load. Create an Envelope and define the SpatialReference property.
• Attempting to use ArcGIS Silverlight components in a page accessed on the file system will return an error. Silverlight applications that contain ArcGIS Silverlight components must be hosted by an HTTP(S) Web site.

Quite a few bugs have been fixed and a few update/enhancements have been added. Note the breaking change. Stay tuned to this page: http://resources.esri.com/help/… which will be update as new builds are released.
