[mapguide-users] How to create Layer and Datasource and link it to SQL 2008 Datasource in code

It's a bit unclear to me what you are asking for.

Do you want to create a FeatureSource by code, a LayerDefiniton, or both?

Both are constructed from xml files, and the xml file definitions can be 
found in the "schemas" subfolder of your MapGuide installation.

The easy way to do this is usually to setup the 
FeatureSource/LayerDefinition in Studio/Maestro
Then save the Xml, and use that as a template for creating new items.
Eg, in the LayerDefinition, change the color, or FeatureSource/Table.

You create a new item by calling the SetResource method on an 
MgResourceService object.

For sample code, feel free to browse the Maestro repository (in C#):

For instance, the MSSQL provider editor is here:
