Layering and Spatial Reference Issues Getting Started

Hi,

I'm getting started with the GIS .Net SDK and I'm having some very basic issues getting started.

I am wanting to use features from my existing file geodatabase. I have published them from ArcMap without any problems as a .geodatabase file and this loads fine in my .net app.

The two main issues I have is that my features do not show up completely on the map if I define a basemap. Sometimes the label for one particular feature pops up, but I can also tell that they are not in the right spot. It's like it is not respecting the spatial reference of my feature tables.

I have tried to base this off tutorial code, but I'm not having any luck.

I define my basemap in XAML, like the Hello World tutorial application. If I comment this out, my features end up drawing fine on a blank grid. I would think that the features should draw fine, because that should be the first layer drawn. On top of that, when the labels for a feature do appear to draw (though nothing else will) I can tell that the spatial reference for the features isn't being used correctly, as they are on the wrong part of the map.

I imagine both of these issues are what are causing my headaches.

I stumbled across one post on this forum that said that local geodatabase tables won't convert on-the-fly when it comes to the spatial reference, so unless I can somehow change the basemap spatial reference (or the local tables I'm importing in code) I might be barking up the wrong tree with this entire thing, which is disappointing.

Sorry but geodatabases doesn't support projection on the fly at this point. Either generate your GDB in the 'correct' spatial reference, or pick a basemap that matches it.
