Pipeline pattern

The pipeline pattern is commonly used in scenarios where we need to execute the asynchronous tasks in sequence:

Consider a task where we need to create a user record first, then initiate a workflow and send an email. To implement this scenario, we can use the ContinueWith method of TPL. Here is a complete example:

static void Main(string[] args) 
{ 
 
  Task<int> t1 = Task.Factory.StartNew(() =>  
  { return CreateUser(); }); 
 
  var t2=t1.ContinueWith((antecedent) =>   { return InitiateWorkflow(antecedent.Result); }); 
  var t3 = t2.ContinueWith((antecedant) =>  { return SendEmail(antecedant.Result); }); Console.Read(); } public static int ...
