How best to use File Version and Assembly Version?

[assembly: AssemblyVersion(Foo.StaticVersion.Bar)]

namespace Foo
{
    public static class StaticVersion
    {
         public const string Bar= "3.0.216.0"; // 08/01/2008 17:28:35
    }
}

[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyCompany("Acme Corporationy")]
[assembly: AssemblyCopyright("Copyright ©  2009 Acme Corporation")]
