我在使用WCF 往数据库里保存数据时，数据库里定义了一个字段为XML类型，当数据保存少的时候没有问题都正常，数据大的时候就一直报错，请大家指教下如何解决，都弄了2天没解决掉！！
代码：
EndpointAddress address = new EndpointAddress(new Uri(Application.Current.Host.Source, "/Services/GetDataEntityService.svc"));
Shareidea.Web.UI.Control.Workflow.Designer.ConfigService.GetDataEntityServiceClient client = new Shareidea.Web.UI.Control.Workflow.Designer.ConfigService.GetDataEntityServiceClient(new BasicHttpBinding(), address);
client.SaveFlowConfigCompleted += new EventHandler<Shareidea.Web.UI.Control.Workflow.Designer.ConfigService.SaveFlowConfigCompletedEventArgs>(client_SaveFlowConfigCompleted);
client.SaveFlowConfigAsync(item);
void client_SaveFlowConfigCompleted(object sender, Shareidea.Web.UI.Control.Workflow.Designer.ConfigService.SaveFlowConfigCompletedEventArgs e)
{
if (e.Result)
{
System.Windows.Browser.HtmlPage.Window.Alert("保存成功！");
}
else
{
System.Windows.Browser.HtmlPage.Window.Alert("保存失败！");
}
}
异常：
{System.Net.WebException: 远程服务器返回了错误: NotFound。
位于 System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult)
位于 System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.<EndGetResponse>b__4(Object sendState)
位于 System.Net.Browser.AsyncHelper.<>c__DisplayClass2.<BeginOnUI>b__0(Object sendState)}
WCF web.config配置：
