Writing “string.IsNullOrEmpty” using pattern matching and comparing the resulting code
I was working on a codebase the other day and it used heavily the pattern matching features of C#. And as I was writing string.IsNullOrEmpty it got me thinking whether I could switch from this very specific method to using (maybe) a more general pattern matching approach. And also, how that compares in performance.

Enumerating over Select’s index
My mind was wandering, as usual when it is not 100% occupied, and I remembered that the Select LINQ function has an overload that gives you the index into the enumeration and it uses an int. So, I thought what’s going to happen if I have longer enumeration and it goes over the range of the int?
