C# - What does the Assert() method do? Is it still useful?

Question

I am debugging with breakpoints and I realize the assert call? I thought it was only for unit tests. What does it do more than breakpoint? Since I can breakpoint, why should

Answer 1

Assert allows you to assert a condition (post or pre) applies in your code. It's a way of documenting your intentions and having the debugger inform you with a dialog if your intention is not met.

Unlike a breakpoint, the Assert goes with your code and can be used to add additional detail about your intention.
