creating services with UI

[mail.microsoft.com]

Hi,

I would like to write a service in C# and I have the need to display a UI
with status information, statistics, etc. If I use the Windows Service
project in C#, I noticed that the System.Windows namespace is not available
to me in the intellisense when I type "using System.".

What is the recommended procedure in C# / .NET for creating services that
display UI's and need to allow interaction with the desktop?

Thanks in advace,
Arvind.
