How to add Descriptions to properties and functions?

[AtWork]

I am trying to add some comments to my class properties and functions that will show in Visual Studio when I hover over a function name on the intellisense menues.

public string DomainName
{
get
{
return DomainName_;
}
}

Lets say I have the above property for a class, is it possible for me to add a description where the description shows up during the intellisense menus?

Thanks!
