Yes you will need to use a GeometryService to project the envelope. You could write the projection logic yourself on the client, which for Mercator is pretty simple. It's even simpler if your data is in WGS84 geographic coordinates (epsg:4326). In that case you can just use the ESRI.ArcGIS.Client.Bing.Transform classes. ... View more

Correct. But neither of those two projections are very suitable for displaying data at the poles because of the large distortion they have in those areas. ... View more

Note that the Map's progress is the sum of the individual layer's progress, so if your layer raises progress=50, that doesn't necessarily mean the map has progress=50 (only if it's the only layer that will be the case). So if your layer is only a small fraction of all the layer's progress (some layers has a heigher weight like for instance tiled layers), you could simply be hitting the fact that the progress value is rounded. I suggest you look at the HeatMapLayer sample to see how progress is raised. ... View more

Is this because the ZoomTo code only executed the first time? Can you zoom in this far? ... View more

This is just how Mercator works. The poles are infinitely far from the top/bottom. That's why most maps cuts off around 85 degrees, because the distortion beyond that point is getting enormous. You are correct there is no way to plot the poles in Mercator. So in other words: This is not a bug but expected behavior. See: http://en.wikipedia.org/wiki/Mercator_projection - What is the limitation of the ESRI.ArcGIS.Client.Bing.Transform.GeographicToWebMercator? -180,-90 -> 180,90 (but note that large positive or negative Y values will converge towards infinity) - What is the limit in terms of WGS84 geodetic coordinates for World Street Map on ArcGISonline (http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer )? -180,-90 -> 180,90. This goes for all geographic coordinates (well if they use degrees that is 🙂 ... View more

Sorry, I am still getting the same error, the Security Exception while trying to connect to the REST Endpoint. Fiddler doesn't provide any errors just says it is trying to connect to the machine through the SSL port (being 443). So are you saying that the app is actually requesting the layer information and map from the services, but the service is returning an error, or are you saying that you don't see any requests going to the service? Does the client access policy file get requested? Do you see anything after that? All this information is important to understand what is going on.

what am I missing though? First of all, a description of what problem you are now seeing happening after these changes? What Initialization failure (if any) do you get on your layer? What is the Fiddler log teling you? ... View more

There's nothing preventing you from creating your own draw tool that does this by using the mouse events. The nice thing about the editing implementation is that you don't have to use the editor to do editing. If you can create the code required for the user to draw a circle, you can simply add the feature to the FeatureLayer.Graphics collection and it will automatically be added to server.

This is likely a bug in the service sample. Could you look into what JSON is being sent? It's likely just a character in one of the strings (layername, description etc) that is not being correctly escaped. ... View more

Is your Silverlight app also hosted on a HTTPS website? Silverlight gets a little picky when trying to talk to HTTPS hosted services.
