Could not build the demo project OledbPointFeatureSource.
Error 1
The type or namespace name 'FeatureLayer' could not be found (are you missing a using directive or an assembly reference?)
C:\Users\rdablo\Desktop\ThinkGeo Sample Projects\ExtendingMapSuiteFeatureSource\OledbPointFeatureSource\MinimumFeatureLayer.cs 5 33 OledbPointFeatureSource
There doesn't seem to be a FeatureLayer class in the MapSuiteCore.dll (3.0.2)
Does the demo reference an unreleased build?
Also noticed that Visual Studio properties of MapSuiteCore differ from the File properties of said same DLL.
