While this is something that a .NET developer doesn’t need to use and care about, I have to point out that QueryPerformanceCounter is a Windows API method that is used by some built-in .NET types behind the scenes. This is considered an outdated approach in .NET development and you need to use interoperability APIs to have access to this function which provides access to a high-resolution performance counter (listing 4).

Listing 4: Using interoperability to apply QueryPerformanceCounter

public static extern void QueryPerformanceCounter(ref long ticks);

In the next section I apply this method to compute the time taken to execute my benchmarks and the main reason is that I want to have a higher precision, so using a more fundamental operating system function can help.
