A bit of historyIn .NET 3.0 we introduced a GC.GetGCMemoryInfo API for library code to get memory load related things (this was used in ArrayPool for example) so it exposed things library folks wanted at the time. In 5.0 I got requests from folks to monitor more things about the GC. Instead of adding a bit of info each time someone asks, I ...

Sprinkle some async and await around, change some return types to be tasks, and badda bing badda boom, you've got an asynchronous implementation. In theory. In practice, obviously I've exaggerated the ease with which a codebase can be made ...

.NET added async/await to the languages and libraries over seven years ago. In that time, it's caught on like wildfire, not only across the .NET ecosystem, but also being replicated in a myriad of other languages and frameworks.

First of all, let me point out that the target audience of this ...
