.NET Core parallel programming samples

The sample source code is a .NET Core Console application written in C#, that implements "grep" functionality across a file system using PLINQ.

Sample prerequisites

This sample is written in C# and targets .NET Core 3.1. It requires the .NET Core 3.1 SDK.

Types and members in use

The sample source code uses the following types and members:

• ThreadLocal
• .AsParallel()
• .AsOrdered()
• .WithMergeOptions(ParallelMergeOptions.NotBuffered)

.NET Standard parallel extensions extras

In 2010, Stephen Toub authored a blog series called "A Tour of ParallelExtensionsExtras". At the time, there was a companion library of extensions that was based on .NET Framework 4. The sample source code has been ported from the original to .NET Standard 2.1.

.NET Core parallel programming with PLINQ

The sample source code is a .NET Core WPF application written in C#, that demonstrates AI algorithms using minimax with alpha-beta pruning, and the parallel AI (light player) uses Tasks and CancellationTokens to achieve speedup via parallelism. For more information, see .NET Core 3 for Windows Desktop.

.NET Core parallel computation of PI

The sample source code is a .NET Core Console application written in C#, that estimates the value of PI using a variety of both serial and parallel implementations. The sample demonstrates elapsed time comparisons between serial execution and parallel functional equivalents. The parallel implementations make use of PLINQ and the Parallel class.

  • .WithCancellation()
  • .WithDegreeOfParallelism()

.NET Core parallel animated ray-traced bouncing ball

The sample source code is a .NET Core WinForms application written in C#, that provides an animated, ray-traced bouncing ball. Sequential and parallel implementations are provided, as is a special parallel implementation that colors the animated image based on which thread was used to calculate which regions. For more information, see Updates on .NET Core Windows Forms designer.
