[mapguide-users] layerdefinitionfactory with .NET

[Kenneth Skovhede, GEOGRAF A/S]

The classes named below can refer either to MaestroAPI classes or Xml 
tag names.
The code given is for the MaestroAPI.
There is no equivalent for the official API, and you will have to do 
this using Xml
manipulation.

Search for a file called LayerDefinition-1.2.0.xsd for a description of 
such a document.

1)
Xsd:
C:\Program 
Files\MapGuideOpenSource2.0\Server\Schema\LayerDefinition-1.2.0.xsd
MaestroAPI:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI

I have shown that in the sample code.

3)
I have included code?
