You don't need a xml stream here, just return the bytes.

public FileResult Download(string id)
{  
    var model = service.GetAllDefinitions().First(x => x.ID == id);
    var definitionDetails = new StatisticDefinitionModel(model);
    string xmlString = definitionDetails.ToXml;
    string fileName = definitionDetails.Name + ".xml";


    return File(Encoding.UTF8.GetBytes(xmlString), "application/xml", fileName);
}
