Although C# 7. 1 hasn’t many new features there are still some convenience hacks I like. One of these is inferred tuple names meaning that we can name tuple members using variable names.

Performance of compiled queries in Entity Framework Core 2.

Before applying any optimizations to our code we have to ask one question: what is the cost of improvement and is it really improvement?
