What problems might I miss by debugging a release build instead of debug build?

Question

Let's say I prefer debugging a release build of my software during development.

What problems might I miss by doing that?

Answer 1

1. There are some optimizations that take place in the Release build. You can see the full list of optimizations here. None of them are supposed to affect the outcome of the program.

2. If you have the DEBUG directive anywhere, that will stay in. Pay careful attention to this, as this could change whole functions.

3. Debug.Asserts will fail in Debug mode but NOT in Release mode.
