A contemporary approach to crafting concise methods in .NET involves using expression-bodied methods. The conventional or expanded method appears as follows:

public Person CreatePerson()
{
    return base.CreatePerson<Person>();
}

Converting this method to an expression-bodied method results in the following:

public Person CreatePerson() => base.CreatePerson<Person>();

I prefer expanded methods for their readability. I was curious to determine if utilizing expression-bodied methods would result in better performance.

Performance Breakdown

The benchmark results show that the performance of expression-bodied methods is 1.4x less performant than that of regular methods.

Prefer a regular method for better readability, unless the expression-bodied method is very short and enhances clarity. In most cases, readability and maintainability should take precedence over style.

Always benchmark any changes using tools like BenchmarkDotNet to ensure your optimizations result in measurable improvements in your actual codebase.
