I've developed a WPF application that has a custom SQL Server database and uses the Esri ArcGIS WPF API to allow users to view, edit and query shapes (features) on a custom map. Maps are created from tiles using the Bing (Quadkey) system. Users can also create multiple layers. This application has a great focus on the editing aspect. Although I use the ArcGIS WPF API from Esri, there are no other services/servers from this company being used for this solution. Layers, features and symbols are stored using custom structures.
So, finally, my question: what would be the "best" (recommended) solution for a web application using custom (tile) maps that should have a great experience to allow users to add/delete/delete features, query, filter and save them? I know that the "best" solution can vary greatly. But what I'm really looking for is some advice from experience users that have done this.
OpenLayers + WFS and GeoServer would be a good match?
