Feature Layer Not Labeling - Is this a bug?

[IanPeebles]

I have an editable feature layer within a application, but it is not labeling.  Is there way to label these features? 
If I add in the map service, the labels appear. 

There seems to be a few bugs with this Silverlight 3.0 Builder. . the .csv export cannot handle null values and feature layers are not editing.

Hi Ian,

It is expected behaviour that the labels do no appear when adding a feature layer. The labeling property is stored with the map service, and is not viewed when a feature layer is added to the application. This is consistent across all of the client platforms.

If you have further questions related to other potential bugs, feel free to post additional details about your specific workflow, or contact ESRI Support Services.
