Source Generators in C# and TDD misadventure time
-
I'm very new to the source generator technology in C# so bear with me, as my information is probably incomplete or inaccurate but what I've discovered so far is amusing and annoying at the same time. I tried to get a source generator referenced from one project for use in another project and I was getting weird results when crawling the syntax tree. I don't even know how to google about the results I'm getting back. It's hard to explain, but it breaks the thing. Creating an incremental generator[^] I followed this code precisely, and it didn't work on my system. However, it will work when I invoke the generator to run specifically as part of a unit test. I haven't had as much luck invoking it outside a test framework. I have no idea why this is. I *believe* (read: hope) it will work when packaged as a NuGet package as well, which is how it was designed to be deployed and used. Of course, I don't want to deploy a NuGet package of code still in initial development. The bottom line for all of this is that this leaves me in the position of being forced to perform Test Driven Development in order to make source generators. I don't know if this is a weirdness with my machine, or perhaps a quirk in this relatively new technology or what, but it's just bizarre to be forced into a particular development paradigm like this.

I will be working on a Source Generator this weekend, my first time too. I was looking at the same article series and a video linked below.

Have a look at this: How to Organize Your .NET Minimal APIs with Source Generator - YouTube[^] When I finish tackling this task, I will publish an article.

Yeah, I just sat through that youtube video to tell me everything I already know, and that nevertheless does not work on my system as advertised. I have to use a test framework to get the damned thing to run at all. Microsoft can get effed. :mad: Edit: IT WORKS! You just have to close VS and reopen it for it to actually take effect. Be nice if somebody said something.

Congrats and thanks for the tip!
