我现在正在撞击虚拟墙几天.BindingOperations.EnableSynchronization方法似乎只在.NET 4.5中起作用.

我写了一个有时失败的测试:

        object blah = new object();

        Application app = Application.Current == null ? new Application() : Application.Current;

            Thread.Sleep(2000);
            w.TestCollection = collection;
            collection.CollectionChanged += collection_CollectionChanged;
            collection.Add(new ThreadSafeObservableTestObject() { ID = 1, Name = "Sandra Bullock" });
            collection.Add(new ThreadSafeObservableTestObject() { ID = 2, Name = "Jennifer Aniston" });
            collection.Add(new ThreadSafeObservableTestObject() { ID = 3, Name = "Jennifer Lopez" });
