Solution items

[C# Programming]

Dear all,

I have a two projects in in my solution.
the first one is a windows service and the second project is a asp.net project.
The purpose of the asp.net website is to cofigure the configuration file(xml file) that the windows service uses.
My question is where to put this configuration file so both projects can reach it?
I putted it in the solution items directory, bud i can't reach it in my code.

Can someone give me a hint?

Thanks in advance.
