There's a lot of great people in the .NET ecosystem, but I don't think GC internals are that relevant for most typical .NET devs.
There’s definitely more there than most .NET devs need to know, but I personally have found learning more about the GC to be incredibly relevant in my day to day work. I would have said the same thing a year ago, now I feel differently, but that is of course heavily inflected by my personal experience.
Similarly you might not expect that reading CLR via C# would make you a better programmer at a high level with things like DI and big frameworks and everything, but it makes you see what you're writing in an entirely different light. A whole other layer below the surface.
I would strongly second that endorsement. I would love a new edition taking the CoreCLR more into account but it’s still more relevant than most any other book I can think of.
Neat! I would definitely like a .NET Core version, though. I was disappointed to discover netmodules were deprecated
Typically, you're right - GC internals aren't usually relevant. That is, until you're fire-fighting a GC-related issue in production. GC internals aren't something you want do a crash-course on while your app burns.
I'd call it a good sign if you can even identify GC-related issues in production. That means all of the other problems that seem to plague .NET shops have been taken care of.
It's always a captivating read for me! I find most discussions about the tradeoffs of GC vs reference counting versus manual memory management are loaded with bias.
I worked with David Fowler he’s really good.
Matt Warren writes a lot of nice stuff about .NET internals and performance.
You're selling Eric Lippert too short
Just offering my personal opinions (by which I mean biases), Eric is also great. Andrew Lock and Steve Gordon are also great choices. Personally, I prefer nuts and bolts .NET writers since there is so much (and much of it good!) DDD/SOLID type content out there.
Jon Skeet, Mark Seemann, Jeff Richter too
Stephen Toub!
If you read one person about .Net GC performance - Maoni is that person.
