class - How do I document a c# dll -

how write class property , method descriptions visible people referencing dll in other projects?

    [description("my age in years attribute")]     public int age     {         { return 0; }         set { }     } 

doesn't work, neither does

    /// <summary>     /// age in years attribute     /// </summary>     public int age     {         { return 0; }         set { }     } 

in visual studio:

project -> properties -> build -> check "xml documentation file".

for further details, see xml comments let build documentation directly visual studio .net source files.
