What are the advantages of hosting WCF Services
in IIS as compared to self-hosting?
There are two main advantages of using IIS over self-hosting:-
There are two main advantages of using IIS over self-hosting:-
Automatic activation
IIS provides automatic activation that means the
service is not necessary to be running in advance. When any message is received
by the service it then launches and fulfills the request. But in case of self
hosting the service should always be running.
Process recycling
If IIS finds that a service is not healthy that means
if it has memory leaks etc, IIS recycles the process. Ok let us try to
understand what is recycling in IIS process. For every browser instance, a
worker process is spawned and the request is serviced. When the browser
disconnects the worker, process stops and you loose all information. IIS also
restarts the worker process. By default, the worker process is recycled at
around 120 minutes. So why does IIS recycle. By restarting the worker process
it ensures any bad code or memory leak do not cause issue to the whole system.
In case of self-hosting both the above features, you will need to code yourself
