How to create a data store with a given schema

    IServerConnection conn = ...;

    FeatureSchema schema = new FeatureSchema("Default", "");
    ClassDefinition cls = new ClassDefinition("MyClass", "");

    cls.DefaultGeometryProperty = "GEOM";
    //Add identity property KEY
    cls.AddProperty(new DataPropertyDefinition("KEY", "")
    {
        DataType = DataPropertyType.Int32,
        IsAutoGenerated = true,
        IsReadOnly = true,
        IsNullable = false
    }, true);
    //Add string property NAME
    cls.AddProperty(new DataPropertyDefinition("NAME", "")
    {
        DataType = DataPropertyType.String,
        Length = 255,
        IsNullable = true,
        IsReadOnly = false
    });
    //Add geometry property GEOM
    cls.AddProperty(new GeometricPropertyDefinition("GEOM", "")
    {
        GeometricTypes = FeatureGeometricType.Point,
        SpatialContextAssociation = "Default"
    });

    schema.AddClass(cls);

    ICreateDataStore create = (ICreateDataStore)conn.CreateCommand((int)CommandType.CreateDataStore);
    CoordinateSystemDefinitionBase coordSys = conn.CoordinateSystemCatalog.FindCoordSys("LL84");
    create.FeatureSourceId = fsId;
    create.CoordinateSystemWkt = coordSys.WKT;
    create.Name = "Default";
    create.ExtentType = OSGeo.MapGuide.ObjectModels.Common.FdoSpatialContextListSpatialContextExtentType.Dynamic;
    create.FileName = "Test.sdf";
    create.Provider = "OSGeo.SDF";
    create.Schema = schema;
    create.XYTolerance = 0.001;
    create.ZTolerance = 0.001;
    create.Execute();
