27. THREADPOOL

28. • WCF, Remoting, ASP.NET, ASMX Web Services
• System.Timers.Timer, System.Threading.Timer
• The parallel programming constructs
• The (now redundant) BackgroundWorker class
• Asynchronous delegates (also now redundant)
We Use THREADPOOL Proudly

32. Tasks can have RETURN VALUEs
Tasks can be COMPOSED
Tasks may or may not use THREADs
Tasks can use THREADPOOL
Tasks can provide CALLBACK APPROACH
Tasks are more powerful with ASYNCHRONOUS functions
