推荐答案

1。两种方法几乎相同。如果您不需要指定TaskCreationOptions或TaskContinuationOptions或TaskScheduler，则建议使用第二个。

有关详细信息，请阅读

StartNew is Dangerous [ ^ ]

和

c＃ - Task.Run（）和Task.Factory.StartNew（）之间有什么区别 - Stack Overflow [ ^ ]



2.我认为在WPF中返回Task没有任何缺点。



如果您需要在方法中与UI进行交互，则必须使用Dispatcher。这是你在问什么？



如果你分享一些你的代码的例子我可以在我的答案中更具体。

1. Both methods do almost the same. Second one is recommended if you do not need to specify TaskCreationOptions or TaskContinuationOptions or TaskScheduler.
For more details you can read
StartNew is Dangerous[^]
and
c# - What is the difference between Task.Run() and Task.Factory.StartNew() - Stack Overflow[^]

2. I do not see any disadvantages in returning Task as a result in WPF.

If you need to interact with UI in your methods you have to use Dispatcher. Is it what you are asking?

If you share some examples of your code I can be more specific in my answer.
