Welcome to the Stryker.NET technical references! In this wiki you will find background knowledge about Stryker.NET and some technical details.

Why Stryker.NET

Before Stryker moved to .NET there already were some mutation testing tools available for mutation testing C# code. None seemed to be able to mutate .NET Core projects. With Stryker.NET we wanted to broaden the mutation test landscape.


Our long term goals are:

  • Offer broad support for .NET projects
    • .NET Framework 4.6+
    • .NET Core 1.0+
    • .NET 5+
    • C#
    • F#
  • Be a blazing fast mutation test framework
  • Have the most detailed reporting experience for tracking down bugs


Stryker.NET is the result of an internship and became open-source in July 2018.
