Which is the best way to start a task in C# (if there are any differences?) The ways I've found but not sure which one to use:

//Using run
Task.Run(()=> MyMethod());

//Using factory
Task.Factory.StartNew(() => MyMethod(); });

//Using action
Task task = new Task(new Action(MyMethod));
task.Start();

//Using lambda
Task task = new Task(() => MyMethod() );
task.Start();


private void MyMethod()
{
   //Do stuff
}

`Task.Run()` is the way to start a task properly. You should never use `Task.Factory.StartNew` – Callum Linington May 19 '16 at 08:11
@CallumLinington Explaining why would be better. – Nasreddine May 19 '16 at 08:13

@Nasreddine I would do, but there are so many answer on stackoverflow for it. – Callum Linington May 19 '16 at 08:14
@CallumLinington, 'should never' until you need explicitly set `TaskScheduler`? – pkuderov May 19 '16 at 08:17
@pkuderov the default one is sufficient in most scenarios, so for the OP he should just use `Run` – Callum Linington May 19 '16 at 08:23
Thank you @CallumLinington @Nasreddine! I will go with new Task. One question, Is the lambda or action a way to go or should I use something else? – Marcus Höglund May 19 '16 at 08:24
Why `new Task`... `Task.Run` surely... Whether you use an action delegate a func delegate or method as the delegate it doesn't matter. It purely depends on what you are trying to do. – Callum Linington May 19 '16 at 08:35
@CallumLinington Yes, Task.Run. Thank you for the response – Marcus Höglund May 19 '16 at 08:37
