Benchmarking applications is the process of evaluating and comparing artifacts with the agreed upon standards. To benchmark .NET Core 2.0 application code, we can use the BenchmarkDotNet tool, which provides a very simple API to evaluate the performance of code in your application. Usually, benchmarking at the micro-level, such as with classes and methods, is not an easy task, and requires quite an effort to measure the performance, whereas BenchmarkDotNet does all the low-level plumbing and the complex work associated with benchmark solutions.
