Here are the things that caught my eye recently in .NET. I’d love to hear what you found most interesting this week. Let me know in the comments or on Twitter.

Capturing the World in Software

If event sourcing is not scalable, faster, or simpler, why use it?
Event Sourcing gives you a complete, consistent model of the slice of the world modeled by your software. That’s pretty attractive.

Conventional

After this tweet by Dave Glick, I found this package that I thought was pretty interesting. Check out the twitter thread for a lot of good info.

I’ve recently become fond of writing unit tests that use reflection to enforce patterns that are too specific for general-purpose analyzers. Stuff like “classes in this namespace are POCO models and shouldn’t have any business logic or methods”. Anyone else do this?

Deserializing JSON into polymorphic classes with System.Text.Json

While working on SpaceDotNet, a strong-typed client SDK to access the JetBrains Space HTTP API, I came across a scenario to deserialize JSON into polymorphic classes. In this post, I’ll explain how to write a custom JsonConverter for System.Text.Json to help with deserialization for such cases.
