Hey, so having an issue with writing out to an xml file. Works fine for single requests via the browser, but when I use something like Charles to perform 5-10 repeated requests concurrently several of them will fail. The trace simply shows a 500 error with no content inside, basically I think they start timing out waiting for write access or something...

This method is inside my repository class, have also attempted to have repository instance as a singleton but doesn't appear to make any difference..

Any help would be much appreciated. Cheers

    public void Add(Request request) {
        try {
            XDocument requests;
            XmlReader xmlReader;
            using (xmlReader = XmlReader.Create(_requestsFilePath)) {
                requests = XDocument.Load(xmlReader);
                XElement xmlRequest = new XElement("request",
                            new XElement("code", request.code),
                            new XElement("date", request.date),
                            new XElement("email", new XCData(request.email)),
                            new XElement("name", new XCData(request.name)),
                            new XElement("recieveOffers", request.recieveOffers)
                        );
                requests.Root.Element("requests").Add(xmlRequest);
                xmlReader.Close();
            }
            requests.Save(_requestsFilePath);
        } catch (Exception ex) {
            HttpContext.Current.Trace.Warn("Error writing to file: "+ex);
        }
    }
