I have been doing alot of reading about remoting, etc. but am still confused
and a little lost.
Problem: I have three applications that all use the same assembly (ie:
MyApp.dll). I want the assembly to be loaded only once (singleton?) and have
it shared between all the applications. So if for example I make a call  
MyApp.SetNumber=2 in application #1, I should be able to make a call
MyApp.ReadNumber in application #2 and get back the value 2. (might be a bad
example here.....).

With application domains, etc this seems like a major pain to do this. Can
anyone help point me in a direction or even give a very basic example of a
shared DLL across different applications? Would it be better (if posslbe) to
make the DLL into a service and do the same thing?

BTW: This is all running on the same machine so it does not need to go
across the network.
