Being able to edit your C# (or F# for that matter) code on your Linux VM from Visual Studio in Windows is pretty great. As a Windows developer, you’re able to work in an environment you know and trust while still being able to experiment — and hopefully produce production code — in Linux, where you may not be quite up to speed. Yet. Visual Studio, that familiar, productive and helpful IDE, is at your fingertips even though your code is far away in a Linux VM.
(Okay, not that far; the VM is running on the Red Hat Container Development Kit on your Windows box, but let’s call that last sentence “poetic license” and move on.)
Editing isn’t enough; we all know that. Since code sometimes has bugs (cough), we need to debug our code. Sure, we can write to a log and check inputs and outputs against expected results, but even that’s not enough. Any kinds of tests, even automated tests (you are using TDD, right? Right?) only confirm the existence — as rare as they are in your code — of defects. Finding the cause of a defect, ahhhh … there’s the rub. If only we could run interactive debugging from within Visual Studio against our compiled C# code running in our RHEL VM.
Well guess what; We can. It’s called “offroad debugging” and it’s not difficult to set up and — this is a technical term — it’s very cool. It’s a bit of work to get set up — not difficult, just several steps — but after doing it one time it becomes very easy for future projects. And never forget; if you get stuck, you can reach me on Twitter (@DonSchenck) or email me at firstname.lastname@example.org.
