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

I have a VS 2010 C# .NET 4 project. The iss开发者_运维百科ue 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.
