which approach is faster: wcf auto generated proxy or channelfactory<t> for consuming services

Question

i have created a wcf service and wanted to consume it in the client application. performance wise, which is better? auto generated classes which are added by service reference or the channelfactory way?

Answer 1

If you step through the auto generated proxy code, you will see that this code uses the ChannelFactory mechanism anyway.

So my answer: the performance is identical.

The only potential difference could be in the code you write around the ChannelFactory calls, which, when compared with the ensuing network call, is effectively zero.
