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.


Check out:

  1. DeepEarth
  2. ESRI's ArcGIS API For Silverlight **

** You can download and use ESRI's Silverlight API for free.

  • 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.

    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.

  • As said by RomaH, Silverlight technology will not see further development. However, it seems that Microsoft will support it until 2021 (goo.gl/rhw5i). Anyway, I think that using this technology in a new development is a bad idea.
