There is a Task, it is necessary that at the time of its execution the button on the form is locked.

Task task = Task.Factory.StartNew(() => { // Тут идёт коннект к БД });

      public async void Start() { button.IsEnabled = false; await Task.Run(() => { //коннект к базе }); button.IsEnabled = true; }

    For .NET 4.0, this option should work:

      public void Start() { button.IsEnabled = false; Task task = ConnectToDb(); task.ContinueWith(task1 => { button.IsEnabled = true; }, TaskScheduler.FromCurrentSynchronizationContext()); } private Task ConnectToDb() { return Task.Factory.StartNew(() => { //подключение к базе }); }
