Hey,

While expanding some functionality to support MapView and SceneView, I ran into some inconsistencies between the two. While not a major issues, I figured I'd mention it, in case it is not yet on your bucket list.

CompositeSymbol with text renders differently in MapView and SceneView.

Summary

MapView, Text outline are not respected (or at least does not render the same)
SceneView: Default TextSymbol alignment is different. Can be modified with OffsetY.
SceneView: Overlapping symbols merge texts - apparently (second image - A + 2 and 3 + 1).
SceneView: Label not displayed (actually rather inconvenient)

var compositeSymbol = new CompositeSymbol();
compositeSymbol.Symbols.Add(new SimpleMarkerSymbol
{
    Color = GetBrush(state).Color.ToDrawing(),
    Style = SimpleMarkerSymbolStyle.Circle,
    Outline = new SimpleLineSymbol
    {
        Style = SimpleLineSymbolStyle.Solid,
        Width = 1,
        Color = Colors.Black.ToDrawing()
    },
    Size = 18
});

compositeSymbol.Symbols.Add(new TextSymbol
{
    Text = priorityText,
    Color = Colors.White.ToDrawing(),
    OutlineColor = Colors.Black.ToDrawing(),
    OutlineWidth = 2,
    FontFamily = "Segoe UI Black",
    Size = 16
});

ToDrawing() just converts System.Windows.Color to System.Drawing.Color

No one else has this question

Text symbol related differences in MapView vs SceneView are already in our backlog and I know our core team is actively seeking ways to improve rendering and symbology so I will share your feedback to the team. Thank you.

Thanks. Will labelling also be addressed? Are there simple considerations I should follow in the latest version to get labels in scene view, or is it currently not supported? I can't remember reading any limitations regarding those, but that doesn't really prove anything

There might be a known issue with SceneView in v100.4 which I'm unable to find but there's been work around this area.. because the following code renders label with current dev build.

GraphicsOverlay and FeatureLayer have a LabelDefinitions and LabelsEnabled property that you can set. LabelExpression can be an attribute key or hard-coded text. Also, MapView has a Labeling property which SceneView currently does not have.

MySceneView.Scene = new Scene();
var overlay = new GraphicsOverlay();
overlay.LabelDefinitions.Add(LabelDefinition.FromJson("{ \"labelPlacement\":\"esriServerPointLabelPlacementAboveRight\",\"where\":null,\"labelExpression\":\"[objectid]\",\"useCodedValues\":true,\"symbol\":{ \"type\":\"esriTS\",\"color\":[0,0,0,255],\"backgroundColor\":null,\"borderLineColor\":null,\"borderLineSize\":null,\"verticalAlignment\":\"bottom\",\"horizontalAlignment\":\"center\",\"rightToLeft\":false,\"angle\":0,\"xoffset\":0,\"yoffset\":0,\"kerning\":true,\"haloColor\":[255,255,255,255],\"haloSize\":2,\"font\":{\"family\":\"Arial\",\"size\":10,\"style\":\"normal\",\"weight\":\"normal\",\"decoration\":\"none\"}},\"minScale\":0,\"maxScale\":0}"));
overlay.LabelsEnabled = true;
var graphic = new Graphic(new MapPoint(0, 0), new SimpleMarkerSymbol(SimpleMarkerSymbolStyle.Circle, Color.Red, 15d));
graphic.Attributes["objectid"] = 1;
overlay.Graphics.Add(graphic);
MySceneView.GraphicsOverlays.Add(overlay);
