Thanks to everyone who attended my live blog yesterday, and to everyone who subscribed. It was so encouraging to see that you like this idea.
As announced yesterday, my live blog will run on a fixed schedule – every Friday, at 14:00 CET (8:00 AM EST) I’ll get online to present a topic and discuss it live with you. This is the schedule for the next two Fridays:
November 20: Migrating Control Add-ins from C/SIDE to AL
This is going to be a live coding session. I’ll take a working control add-in developed in a mish-mash of tools we used to develop them back in the stone age, and migrate all that into AL. I’ll present two viable approaches for this, that I’ll call a “white box approach” and a “black box approach”.
While doing this, I’ll also discuss what can be done, what can’t be done, and things you want to watch out for while performing the migration.
November 27: Fun with Interfaces
Again, a mostly live coding session. I’ll present AL interface type, what it’s good for, and how to use it. Of course, I’ll address the usage through enum type, but I’ll also talk a lot about other use cases. Interfaces allow us to fix some old and long-standing anti-patterns, and introduce some nice new patterns, and you can expect me talking about that, too.
It was great to see that – when I asked about what topics you’d like to see me cover – there were both interfaces and design patterns in AL. It tells me we are on the same page here.
December: You tell me
I have no firm plan for December yet. I actually want you folks to have most of say in what my live blog will be about. Yesterday, you gave me some ideas and today I want to let you choose.
In the poll below, select up to two topics you’d like me to cover in the first two live slots in December.
Pick your favorite live blog topics for December 2020
- AL design patterns (29%, 22 Votes)
- Add-ins best practices and anti-patterns (26%, 20 Votes)
- Setting up DevOps for Control add-ins (25%, 19 Votes)
- Adding own code actions to VS Code (13%, 10 Votes)
- Troubleshooting Azure Functions (8%, 6 Votes)
Total Voters: 47
The poll runs until noon on November 19th, the top two answers will be my topics for December 4 and 11.
What topics do I have in mind?
Other than the topics you (will/have) suggest(ed), I have a few topics of my own that I’d like to bring some attention to:
- Musings around transaction control in AL. We’ve had
AssertError Error('')for a long time, and now we don’t (really) have it anymore. We need to fall back to (or simply keep relying on)
if Codeunit.Run(). But this is very limited in terms what and how we pass state between caller and callee. This will be a “let’s code and theorize together” kind of session, more about discussing what we have and where we would like to go from here and why, than presenting actual “how to this or that”.
- Musings around event infrastructure in AL and BC runtime. Personally, I’ve never been totally convinced that the events – the way they work – are the best we could possibly have. Don’t get me wrong – they are amazing at allowing us to build loosely-coupled architectures and to seamlessly plug in our code into other people’s code. But there is much more they could be if Microsoft wanted to take an extra step. I’d love to discuss this topic with you. Who knows, maybe we manage to convince Microsoft that we need a bit more push here. Or maybe you manage to convince me that I am getting it all wrong. Who knows.
Let me know in the comments what other topics you’d like me to cover, and also what you think of these topics I suggest here. Enjoy the weekend, and see you next Friday!
