WpfExceptionMessageBox 1.0.1

WPF Exception MessageBox

The WPF Exception MessageBox is a custom gui MessageBox specifically designed to display the details of an Exception object to the user for debugging purposes that targets the Microsoft Windows Presentation Framework (WPF).

This project is currently available for Core 3.1 and NET 5. Support for NET 6 will come out soon.

To use the WPF Exception MessageBox, simply put this in a catch statement:

//...
using WpfExceptionMessageBox;
//...
    try
    {
        // Do something wrong here
    }
    catch (Exception e)
    {
        // TO quickly display the exception, just pass
        // the exception to the static show method.
        _ = ExceptionMessageBox.Show(e)
    }

The ExceptionMessageBox.Show static method has multiple overloads that allows customization of the message box title and severity icon that is displayed in the box.

Default Display:

Display with Informational severity:

Display with Warning severity:

Additional Exception Details Window:

You can also provide additional help to the user by adding a link to additional help details to the thrown exception:

            try
            {
                throw new OutOfMemoryException();
            }
            catch (Exception e)
            {
                e.HelpLink = "https://dotnet.microsoft.com/";
                _ = ExceptionMessageBox.Show(owner, e, ExceptionSeverity.Warning);
            }

Additional Exception Details Window with Help button:

The exception details can be copied from the message box so that they can be easily saved or emailed to someone else for additional analysis.

This is how the exception details will look when copied from the exception box. This example is for a thrown AggregateException object, which the message box will capture all inner exception details as well as the parent exception:
