.NET Debugging Tips
A collection of tips for debugging .NET applications.
Debug Tip #1: Conditional Breakpoints
What: a breakpoint that's only hit when a condition is satisfied
How: right-click a breakpoint, select Conditions, then write your expressions (with IntelliSense support)
Why: when you want to debug a specific case in an iteration
Docs: https://docs.microsoft.com/en-us/visualstudio/debugger/using-breakpoints?view=vs-2022

Debug Tip #2: Data Breakpoints
What: a breakpoint that's only hit every time the value of a variable changes
How: right-click a variable, click on the "Set Data Breakpoint" menu item
Why: when you don't know when/how a value is changed
