I was curious what the differences are between the debug and release modes of the .NET compiler and came across these questions about debug vs release in .NET and reasons that release will behave differently than debug. Up to this point I really haven't paid much attention to these compiler modes. Now I will.
My question is, assuming that I am using a testing framework (NUnit) and TDD, would I run into any issues if I simply always compiled in release mode?
You're using TDD. You write your test. The test fails. You write the code to pass the test. The code fails. You look at the code you wrote and can't see any obvious reason why it fails. Do you reason some more or start up the test in the debugger (using TestDriven.Net) and step through the test? Maybe I'm just not smart enough to always figure out why my code doesn't work, but I usually do the latter when I'm stumped.
