Question
What is the best way to handle an unhandled exception in a WPF application?
Solution
You can use DispatcherUnhandledException
:
XAML (App.xaml):
<Application x:Class="App.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="wndMain.xaml" DispatcherUnhandledException="Application_DispatcherUnhandledException">
Code Behind (App.xaml.cs/vb:
private void Application_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
{
// Handle error here
...
// Prevent default unhandled exception processing by WPF
e.Handled = true;
}
Read up more here. Always do the correct amount of error handling in the first place though. Don't just let errors slip into this method.
