I really enjoyed participating to the last 2codeOrNot2code, so I'm happy to repeat the experience. This time, we will have some fun with functions, unveiling interesting details about what happens when you call them. If you like to understand how things work, don't miss it!
Let's inspect "The hidden life of method calls" in #dotnet via #CSharp with @kevingosse.net.
