Question

I need to project the bing maps to Wgs84 UTM Z19S It can be done? thanks for the help xmlns:bing="clr-namespace:ESRI.ArcGIS.Client.Bing;assembly=ESRI.ArcGIS.Client.Bing"

Most generally, the tiled map service is driving the spatial reference of the map, then other services have to be projected in this spatial reference.

Just to clarify this: The first layer defines the spatial reference (unless you explictly set it). If a tiled layer doesn't match this spatial reference, it will simply not render. 
So from an applications perspective it's the first layer that drives the SREF, but from a conceptual perspective, the tiled layers should define the spatial reference (if its not the first layer, you as a developer need to explicitly set the spatial reference).

The bing map is a cached tiled map service and is only available in Web  Mercator.
So you can't project bing maps tiles to UTM Z19S.
