New Post: R in WCF and return large set of Data

Thank you for your feedback.

Yesterday, we have tested in Console App, and it working normaly.

So we test to use our WCF self hosted (in console App).
And the result was good. No crash, console app continue to work. No problem after several calls of the service.

I think IIS perform some actions on the memory.
Finally we keep Self hosted solution (We can also try to use Windows Services host)

Regards,
Thibaud
