i have a little decision-problem
I create a new server-application which works together with client-applications. The Server-Application must manage the users, which are signed in and are online. So... how should i save this informations? Is it better to store it in the RAM (i make a List<onlineusers> where the Classes with the UserInformations are in there), or should i better save them in a DB, where i have the passwords and so on too? My Problem is, i don't know how many users will use this client-application! There could be 100 users or 10 000 users!
But this wouldn't be the problem, the big problem is, that this server only exchange user-informations, and so if i have maybe 10 000 users and a lot of users asking for informations about other users i could get in trouble if i have the data in the RAM (maybe not enough RAM?) and if i have it in a DB i have a very big HardDisk IO! The TCP-Connections at last i MUST store in the RAM of course, so anytime i need informations in the RAM about my Users...
So, has somebody any idea which technique i should use to get the best performance out of it?

I have a windows service. I want to write an (C# .net) application that users run to communicate with the service. There is no restriction on .net version but security is important. What solution do you suggest?
I did a bit of research and found out named pipes and LRPC are good choices among other technologies. However it looks like in .net we'd better use WCF which, for IPC, supports named pipes. But WCF seems to have a steep learning curve. So I decided to ask you before I start to learn it.
Thank you very much for you help in advanced.
