An AL developer gets fired from his job for writing inefficient tests. With his LinkedIn profile proudly showing off his extensive testing experience, a car manufacturer hires him to test cars. His first assignment: test the oil lamp. So he imagines a test, applying his vast experience:

// [GIVEN] A car
// [GIVEN] Enough fuel
// [GIVEN] Engine oil within operational limits
// [GIVEN] Engine runs long enough

// [WHEN] Oil level drops below operational minimum

// [THEN] The oil lamp turns on

Spoiler alert: the guy’s gonna get fired again.

Long time no see, eh? Time flies, what do you know…

I am thrilled to still find you here. Honestly, I wasn’t sure this morning if I was about to even find this blog where I left it seven months ago. Cool to find both my blog and you in good shape, patiently waiting for my contribution.

This morning I had a call with a partner asking if it was possible to deploy a control add-in in such a way that other partners could use its functionality from their own extensions. My answer was, and it still is – well, it should be possible, but I don’t know for a fact because I never tried it.

So let’s try it and find the answer together.

Directions US 2016 (yes, 2016, sorry y’all who got the 2017 link in your mailbox) was quite an event. As Directions always is, a lot of people, enthusiastic about this market we strive to thrive in, and about the product we love no matter the limitations we often face when we aim for better, more scalable architectures.

If anything, it reminded me of a long to-do list I have had around for this blog for a while, and I decided to start cleaning it up. The topic of my main session this year was loose coupling of dependencies (I called it polymorphism, because that’s what I’d ultimately like to see possible in C/AL) and I presented two patterns I came up with during my past few years.

Before I present them here on my blog, I wanted to put them in a broader context: loose coupling. So, this is what this post is all about: explaining what loose coupling is, how to achieve it in C/AL, and why you will not want to live without it ever again.
