    Example
    Creating a feature class
    // Create a Cities feature class with the following fields
    //  GlobalID
    //  ObjectID
    //  Name (string)
    //  Population (integer)
    
    // This static helper routine creates a FieldDescription for a GlobalID field with default values
    FieldDescription globalIDFieldDescription = FieldDescription.CreateGlobalIDField();
    
    // This static helper routine creates a FieldDescription for an ObjectID field with default values
    FieldDescription objectIDFieldDescription = FieldDescription.CreateObjectIDField();
    
    // This static helper routine creates a FieldDescription for a string field
    FieldDescription nameFieldDescription = FieldDescription.CreateStringField("Name", 255);
    
    // This static helper routine creates a FieldDescription for an integer field
    FieldDescription populationFieldDescription = FieldDescription.CreateIntegerField("Population");
    
    // Assemble a list of all of our field descriptions
    List<FieldDescription> fieldDescriptions = new List<FieldDescription>()
      { globalIDFieldDescription, objectIDFieldDescription, nameFieldDescription, populationFieldDescription };
    
    // Create a ShapeDescription object
    ShapeDescription shapeDescription = new ShapeDescription(GeometryType.Point, spatialReference);
    
    // Alternatively, ShapeDescriptions can be created from another feature class.  In this case, the new feature class will inherit the same shape properties of the existing class
    ShapeDescription alternativeShapeDescription = new ShapeDescription(existingFeatureClass.GetDefinition());
    
    // Create a FeatureClassDescription object to describe the feature class to create
    FeatureClassDescription featureClassDescription = 
      new FeatureClassDescription("Cities", fieldDescriptions, shapeDescription);
    
    // Create a SchemaBuilder object
    SchemaBuilder schemaBuilder = new SchemaBuilder(geodatabase);
    
    // Add the creation of the Cities feature class to our list of DDL tasks
    schemaBuilder.Create(featureClassDescription);
    
    // Execute the DDL
    bool success = schemaBuilder.Build();
    
    // Inspect error messages
    if (!success)
    {
      IReadOnlyList<string> errorMessages = schemaBuilder.ErrorMessages;
      //etc.
    }
