[mapguide-users] layerdefinitionfactory with .NET

[Zac Spitzer]

you will need to port over this code to .NET

C:\Program Files\MapGuideOpenSource2.0\WebServerExtensions\www\mapviewerphp\layerdefinitionfactory.php

it only supports a subset of the functionality available, to do
anything more try reverse engineering existing layers
