c# - WSTrustChannelFactory as a singleton. Is it the best practice?

Question

I'm working with an application that uses WSTrustChannelFactory to create trust channels, I noticed that the code is creating a new WSTrustChannelFactory everytime a new channel is needed.

I've never worked with this before but since this is a factory I suppose it can be implemented as a singleton.

Am I right? If so, is there any additional consideration to take (will the factory always be "usable" or there are any scenarios/exceptions where it should be replaced with a new instance)?. Also, is the factory creation an expensive operation, such as a WCF ChannelFactory creation?

我对吗？

是的，我认为你是。我参与过几个我们使用 a 的项目，channel factory而且每次都是singleton. 它当然有其局限性，并且在非常高的负载下可能成为瓶颈，但对于很多实现我认为你很好。
