We have a application base on ArcGIS Runtime for WPF.
The application has a socket client and connect to a socket server in the same process (ArcGIS works as a user control).
But when the socket client started, the Map's YMax become infinity and the Navigation Control's FullExtent lost function and other LocalGeometryService's projection also misfunctioned.
Does anyone known how to deal with it?
