C# Source Generators - Write code that writes code - David Wengier

Generating source code is not a new technology, and there are lots of different offerings out there available for you to use, or that you may in fact be using right now. Tools like PostSharp, Fody, CodeSmith, and many, many more. What is new however, with C# 9 and .NET 5, is a formal source generation offering from Microsoft, taking advantage of a unique opportunity that only the Roslyn team can provide, that lets you run your generator inside the compiler pipeline, with access to the internal data structures the compiler produces. In this session we'll cover source generators in general, deep dive into the C# 9 offering, and then run through some examples, talk about the possibilities, and leave you with no shortage of ideas for your own generators that you can run wild with. When all you have is a hammer, everything looks like a nail, and with source generators in your toolbelt, you won't look at that slow old reflection code the same way ever again.

On the AutoNotify example it really kills me that you have to put the generator attribute on the private storage field and not the public property. Storage field is internal implementation detail but is visible in the code, where as the property which is the class public interface is missing

I don't understand why there's so much boilerplate required in order to get this working. Seem like it should be possible make it work just by referencing the generator stuff, and start writing generators, without doing any setup in the csproject file.

sourcegen.dev is no longer up?

Does anyone have any considered opinions about Fody?

Nice video.
Horrible Audio jitter from time to time.

Too many ads in the middle of whole video, impossible to watch.

To get around this problem on videos that I REALLY want to watch, I use a TH-cam video downloader to download the video as a .mp4 file and watch it that way. No ads. I bought one for 10 bucks about 6 years ago. 10 dollars well spent.
