Willy has a point. If the command line camera support works, then you can take that route.
I tracked down my old C# test program for LDVLib. I'm not sure if it still works, but its VS2010 source code is here:

Note that you have to manually copy LDVLib.dll into the same directory that the .exe file is in before you run the program. As I already mentioned, LDVLib itself won't let you take snapshots. You can do a screen capture of the LDVLib rendering window, but you have to be absolutely sure that nothing else is obscuring it, and you would be limited to image sizes that fit on the screen.
