How do I allow breaking on 'System.NullReferenceException' in VS2010?

Question

I have a VS 2010 C# .NET 4 project. The issue is that the program is not breaking on 'NullReferenceException' errors during debugging.

The output window will display the following:

A first chance exception of type 'System.NullReferenceException' occurred in myProgram.exe

...but the debugger will just exit out of the function and continue running the rest of the program.

How do I change this behavior so that the debugger will break on these exceptions?

Go to Debug -> Exceptions -> Search for NullReferenceException and check the "thrown" checkbox.

Wow.. 3 years I have been wondering how to do that. I should really use more button in VS than build and run. – AnotherUser Jun 25 '14 at 18:31
Shortcut is CTRL + ALT + E – Ozzy Sep 06 '18 at 13:00

It is now hidden in Debug > Windows > Exception Settings. – levininja Apr 16 '19 at 19:10
In Visual Studio 2012: DEBUG > Exceptions... then click Find... – Mark Davich Jun 29 '21 at 19:40
