Try-Catch-Finally block problems with .NET4.5.1

Question

I have a simple try-catch-finally code block that works as expected in .NET3.5, but the same code behaves completely different on a project created with .NET4.5.1. Basically

Answer 1

Prior to Framework 4.0 unhandled exceptions launched 'Microsoft .NET Error Reporting Shim', which shows the dialog offering to 'Debug' or 'Close program'. The shim allows .NET applications to close "cleanly".

Starting with Framework 4.0 (as far as I can tell) unhandled exceptions result in Windows launching Windows Error Reporting (WER) which shows-up as Windows Problem Reporting in Task Manager. This application shows a similar dialog to the shim but takes a more hardline approach to killing the application, probably calling TerminateProcess or TerminateThread which would not allow any further code to execute in the misbehaving process.
