WCF-自托管还是IIS首选项？

Question

I am relatively green with C# and WCF. I have landed on a project where I am creating self hosted WCF services running as Windows services but am starting to wonder if I should use IIS instead (which we don't currently use) as managing all of these services could eventually get cumbersome.

Despite my best efforts, I have yet to find any definitive information about why I might favor one approach over the other. The services are primarily used for utility stuff like resizing images, retrieving files, etc. and are called by both C# and Java clients.

Thanks

Answer 1

The shortest answer would be 'it depends'. On your requirements. You can self host without problems, but IIS will manage resources more effectively and enable you to fine tune stuff more easily than self-hosted.

For instance, in IIS would be more simple to deploy a new version or remove and old one.

Answer 2

Either way is fine.

Generally, using the builtin IIS hosting capabilities can make deployment and configuration simpler for you. Also you have the activation model of http.sys - which means IIS will start the necessary process for you when an appropriate message arrives.

Clients of any platform can connect to the WCF services regardless whether they are self-hosted or IIS hosted.
