问题
On my other machines Visual Studio always broke on errors when there was not a try/catch to handle them, but if there was a try/catch then it didn't break. For some reason on this laptop it doesn't work that way. It didn't break at all at first, but then I found out how to set it to break by going to debug/exceptions. However, configuring it to break there causes it to always break on exceptions even if there is a try/catch block.
How do I make it work like I'm used to??

Make sure you have Just My Code Enabled by going into Tools-->Options-->Debugger-->General--> Enable Just My Code. This will change your Debug--> Exceptions Dialog Box to show a CheckBox for User-unhandled Errors.
