In previous part we lerned how to pass parameters to a Source Generator. In this article we need this knowledge to pass futher parameters to implement logging.

In this article we will see how to pass configuration parameters to a Roslyn Source Generator to control the output or enable/disable features.

In this article we will see how to reduce the resource consumption of a Source Generator when running inside an IDE by redirecting the code generation to RegisterImplementationSourceOutput.

As a backend developer you have to implement some kind of periodically running background jobs from time to time. Most widely used tools I see are timers, tasks, semaphores, half dozens of booleans and enums to keep the state. Depending on the complexity of the code, understanding it can be quite adventurous. Alas, almost none of the developers I asked about reactive extensions (Rx.NET) know that they even exist.

With the version 4.3.1 of Microsoft.CodeAnalysis.* Roslyn provides a new high-level API – the method “ForAttributeWithMetadataName”. Although it is just 1 method, still, it addresses one of the biggest performance issue with Source Generators.

There is this popular quote by Jamie Zawinski: Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems.”



In this second article of our short performance series, we want to look at the latter one of those problems.
