I want to build a wpf/silverlight mapping application that enables real-time visualization of features in a map, and that allow different users to add features (points, polygons) to the map. My initial thought is to use WFS-T for this purpose, but unfortunately, I cannot find any free/cheap SDK that provide support for WFS-T within WPF. My question is therefore:

Does anyone know about a free/cheap SDK that enable support for WFS-T within WPF applications?

p.s. there's no need to mention ArcGIS products as an alternative, I can't afford them.

Thank's for your attention.

ESRI's ArcGIS API for Silverlight only support featurelayers that are hosted on an ArcGIS Server (which cost an immense amount of money). DeepEarth does not mention any support for WFS-T. – user5714 Jan 31 '12 at 20:34
I might suggest though finding an alternative to developing on a Silverlight API. Silverlight is being decommissioned and will no longer developed. Though ESRI might support it for a while just keep that in mind when determining the product cycle of your application. – RomaH Dec 7 '12 at 23:35
As said by RomaH, Silverlight technology will not see further development. However, it seems that Microsoft will support it until 2021 ( Anyway, I think that using this technology in a new development is a bad idea. – dariapra Dec 8 '12 at 3:18
