Hi,Currently the labelling capability is not as rich as was available in ArcObjects. We're working to resolve that gap and will be providing additional labelling functionality in the new ArcGIS Runtime SDK for .NET which will be released in 2014 (and contains a new, improved WPF API).Until then, you could investigate using the geometry service operation LabelPoints and then add TextSymbols at those locations. Alternatively, if your solution involves local dynamic map services or online dynamic map services, you can override and define the labelling of layers in those services.CheersMike
