Show Notes

"The first measurement could be actually someone from the, so-called business, stating that, "oh gosh, this is so slow." That would be like the coarse grained measurement that you can sometimes receive for free"— Szymon Kulec

Hey everyone, and welcome back to The Modern .NET Show; the premier .NET podcast, focusing entirely on the knowledge, tools, and frameworks that all .NET developers should have in their toolbox. I'm your host Jamie Taylor, bringing you conversations with the brightest minds in the .NET ecosystem.

Today, we're joined by Szymon Kulec to talk about systems programming in .NET. But that's just the surface level detail of what we talk about. We do a deep-dive into some of the corners of .NET and C# that a lot of engineers hardly ever get the chance to cover. This is more than your standard, surface level conversation about C# and .NET.

"Maybe sometimes you will actually create a thread. Something that you don't do nowadays in .NET, because you know what you are doing and you want to own the specific thread for or your own specific purpose."— Szymon Kulec

Along the way, we talked about how developers who are using C# and .NET should think about learning the deeper levels of the language and how things work under the covers. Knowing how the JIT works with your code will help you to write more performant code, for sure.
