Question

For long runnings tasks(Asynchronous) in C# 4.0 windows Application.

The choices are:

1. BackgroundWorker (Thread Pool)

2. Thread

The above two are recommended for long running tasks(throughout application lifetime). Any other choices? In Additon,

• BackgroundWorker – Uses ThreadPool Thread and for long running process with UI updates.

• Thread – User defined Thread (Thread Creation overhead etc.) and for long running process (can use priority)

  Which would be a best choice

  1. if no need for UI update,priority and for Thread (which is created only on application/process start)?

  2. if number of tasks increased? (Care of ThreadPool Starvation)

Any other interesting things?

Answer 1

For long runnings tasks(Asynchronous) in C# 4.0 windows Application.

You would probably use a Task (TPL) with the LongRunning option. The TPL also runs on top of the ThreadPool but the option can make it reserve a thread.

if number of tasks increased? (Care of ThreadPool Starvation)

The ThreadPool will try to dynamically adapt, and you have the option to help it a little.
