Yes, you can do just that.
Look in the Maestro source code to see how it's done.
The files "ResourceEditors/ResourceEditorBase.cs" and "ResourceEditors/ResourceEditorGeneric.cs" shows it.
Some more customized versions are avalible in eg "FeatureSourceEditorSDF.cs"

Basically you can do:
MaestroAPI.ServerConnectionI con; //You must initialize this, see the developer docs
   MaestroAPI.FeatureSource fs = new MaestroAPI.FeatureSource();
   fs.Provider = "OSGeo.SHP.3.1";
   fs.Parameter["DefaultFilePath"] = "C:\my.shp";
con.SaveResourceAs(fs, new MaestroAPI.ResourceIdentifier("my fs", OSGeo.MapGuide.MaestroAPI.ResourceTypes.FeatureSource));


As for your actual problem, does the server error log show anything?
C:\program files\Mapguideopensource2.0\server\logs\error.log

Thanks for the reply. Unfortunately that did not solve my problem and I got
the same error. Is there anything else I could try?

I was not aware you could do this without generating/manipulating the xml.
My web tool has to fully control setting up data sources. So the user
selects a provider and then fills in the connection details. I then need to
create a new data source from this to be stored in mapguide. Can you do this
using the Meastro API alone?

I believe the problem is the .Net UTF-8 Encoder prefixes an UTF-8 BOM,
which causes problems in the Xml parser:

You can try to create the UTF-8 encoder with:

UTF8Encoding utf8 = new UTF8Encoding(false);


And see if the problem goes away.
Alternatively you can use the MaestroAPI instead of messing with the raw Xml:
