Subject: .NET Application Profiler?

Hello all,
I have a client who would like to know which tool(s) can be used to profile a .NET application (.NET Windows Service that calls one or more .NET class libraries) to determine where performance problems might exist.  They would like to collect information about the application including amount of time spent in each class method and information on "functon dispatches".
