Application.Current.Dispatcher.BeginInvoke - Where to place Try & catch?

if I have a dispatcher invoking in background like this:

Application.Current.Dispatcher.BeginInvoke(new Action(() => MethodToCall()), DispatcherPriority.Background);

Should I have wrap the code above inside a Try & catch or place the try & catch inside the MethodToCall() method?

Many Thanks,

Hi BeginInvoke will Execute your Method in anoster Stack. So a try-catch around "Application.Current.Dispatcher.BeginInvoke" will not work.

You need to do something like this:

Application.Current.Dispatcher.BeginInvoke(() => {
try
{
    MethodToCall();
}
catch
{
   //handle
}
), DispatcherPriority.Background);

or simply in "MethodToCall".

If you really have a case for catching a specific exception then the try { } catch should be placed inside MethodToCall.
