Using Thread is pretty straightforward
Thread thread = new Thread(MethodWhichRequiresSTA);
thread.SetApartmentState(ApartmentState.STA);
How to accomplish the same using Tasks in a WPF application? Here is some code:
Task.Factory.StartNew
(
() =>
{return "some Text";}
)
.ContinueWith(r => AddControlsToGrid(r.Result));
I'm getting an InvalidOperationException with
The calling thread must be STA, because many UI components require this.
You can use the TaskScheduler.FromCurrentSynchronizationContext Method to get a TaskScheduler for the current synchronization context (which is the WPF dispatcher when you're running a WPF application).
Then use the ContinueWith overload that accepts a TaskScheduler:
var scheduler = TaskScheduler.FromCurrentSynchronizationContext();
Task.Factory.StartNew(...)
.ContinueWith(r => AddControlsToGrid(r.Result), scheduler);
