Getting ready for the new ArcGIS Runtime SDK for the Microsoft .NET Framework

Question

Last summer we announced in this blog post we were working on a new SDK called ArcGIS Runtime SDK for the Microsoft .NET Framework. This SDK would take all our experience building APIs and SDKs for the Windows desktop, Windows Phone and Windows Store app platforms, and bring them together in one SDK. Since the announcement, we know many of you have been thinking about code and skills you have developed with the existing ArcGIS Runtime SDK for WPF and asking how you can best plan for a transition to the Windows Desktop API included with the new .NET SDK.

This" rel="nofollow" target="_blank">http://blogs.esri.com/esri/arcgis/2014/03/07/getting-ready-for-the-new-net-sdk/]This blog post will help you prepare for the arrival of the new SDK by providing tips you can follow today in the current WPF SDK.

Hi,

We have now included a sample to demonstrate how to perform Hittesting on a MessageLayer - it is currently in the v.next branch until the product is released: arcgis-runtime-samples-dotnet/MessageProcessingSample.xaml.cs at v.next · Esri/arcgis-runtime-samples-dotnet · GitHub

Hi Mike,

Wondering if you could help me with this error ..

Unable to cast object of type 'CoreMessageGraphicsLayerWrapper' to type 'RuntimeCoreNet.CoreGraphicsLayerWrapper'.

while trying to a called MessageGraphicLayer.HitTestAsync(..)

Graphic graphics = await msggraphiclayer.HitTestAsync(EsriMapView, point); or

or IEnumerable<Graphic> graphics = await graphiclayer.HitTestAsync(EsriMapView, point, 1);

I am using the Esri.ArcGISRuntime.AdvancedSymbology and the MessageLayer to process 2525B messages and I would like to be able to select the graphics (eg using hit test) and obtain the graphics and do something with it.  But time I try to called the HitTestAsync, I get the error above and I go no idea what it saying.  Can you help?

foreach (var layer in MsgLayer.ChildLayers)

{

if (typeof(MessageGraphicsLayer) == layer.GetType())

{

MessageGraphicsLayer msggraphiclayer = (MessageGraphicsLayer)layer;

try

{

Graphic graphics = await msggraphiclayer.HitTestAsync(DrawingLayers.EsriMapView, point);

}

catch

{

}
