For anyone searching for GML support in MapGuide... 

Firstly I know that GML is really a transfer or interchange format and not,
as such, a spatial data format suitable for regular access.  It is a verbose
XML file with no spatial index.

At present there is no (obvious) third party build for OGR for MapGuide 2.6
because it requires a MSVC 2012 compatible build.

But for MapGuide 2.5.x we can use OGR from the nice folk at GISInternals.
I downloaded 1.9.2 from here: (this is x64)
http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-x64-gdal-1-9-2-mapserver-6-2-0.zip
<http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-x64-gdal-1-9-2-mapserver-6-2-0.zip>  

>From the downloaded ZIP file copy GDAL19.dll and put into your
OSGeo\MapGuide25\Server\Fdo folder (backing up the original first of
course).  If you have open GDAL/OGR connections the file will be locked and
you will need to stop the MapGuide25 service first.

There are other dependencies (thanks to DEPENDS.EXE) and you should also
copy the following files: 
  geos_c.dll
  iconv.dll
  libcurl.dll
  libeay32.dll
  libexpat.dll
  libmysql.dll
  libpq.dll
  openjpeg.dll
  proj.dll
  spatialite.dll
  ssleay32.dll
  xerces-c_2_8.dll
  zlib1.dll

You will now be able to create a FeatureCourse connection to a GML file.

This should probably go on the Wiki if it's not there already!
