Has anyone been successful using the RenderingService using release 2.0.2? It
does not seem to be working for me. My install is MGOS 2.0.2 ,.NET, and IIS.

I am trying to save a map as a PNG to my local drive. 

I get the following error: "An unclassified exception occurred." and no file
is created. Yes, c:\temp exists. :) 

Sample C# code:

MgByteReader byteReader = renderingService.RenderMap(map, selection,
mapExtent, 650, 650, bgcolor, "png" ); 
MgByteSink byteSink = new MgByteSink(byteReader); 
string fileName = "c:\\temp\\myMap.png"; 

Any suggestions or success stories would be welcomed.
