فرق بین ++i و i++ در زبان سی شارپ
سلام؛ وقتی در قسمت:
یک متد Async قرار میدم
IoCWrapper.RunAndDispose(() => { var draftsService = IoCWrapper.GetInstance<IBlogPostDraftsService>(); draftsService.RunConvertDraftsToPostsJob(); });
IoCWrapper.RunAndDispose(async () => { var draftsService = IoCWrapper.GetInstance<IBlogPostDraftsService>(); await draftsService.RunConvertDraftsToPostsJobAsync(); });
دفعه اول به درستی اجرا میشه، ولی دفعه دوم خطای زیر میده
System.ObjectDisposedException HResult=0x80131622 Message=The ObjectContext instance has been disposed and can no longer be used for operations that require a connection. Source=EntityFramework
