Hi Jason! That’s correct. Currently (limited time offer) there’s a monthly subscription available, which is a great deal. I hope that helps

MediatR shines when you have: large teams, complex workflows & multiple cross-cutting concerns.

Otherwise, it’s like using a chainsaw to slice bread.

I believe you can even find the explanation in the docs.

I can see the concern with some upgrades going unnoticed

I can see you upgrading without even noticing any breaking change; however, some things fundamentally changed.

Honestly, I would prefer a regular upgrade to the old package, but they have thought about it.

Using MediatR everywhere because it looks 'professional'?

Think again.

Often, direct service calls are simpler, faster to debug, and your future self will thank you.

Gui Ferreira @guiferreira.me · Sep 8

Basically, they want the users to make a conscious decision to upgrade due to all that is involved.

I'm sorry for not getting back to you sooner, Xavier.

I think it could work. Maybe it would need some kind of prompts to tune the output to what the user wants. But looks like a good idea

Interesting. How would we ensure consistency across versions? 🤔

Watched a senior dev spend 3 days testing code that took 2 hours to write.
Why? He wrote it backwards.

Most C# devs do.

I did too—until I learned to write code that wants to be tested.

I packed 15 years of lessons into a 4h course.

Any hacks for organising YouTube recommendations by mood/interest?

I wish I could filter recommendations into buckets. Imagine toggling "Baking Mode" only to see sourdough tutorials instead of mixing them with coding videos.
