In their own words
Coverlet
Coverlet is a free, MIT-licensed code coverage framework for modern .NET SDK-style projects. It measures line, branch, and method coverage across Linux, macOS, and Windows. Before tests execute, Coverlet instruments assemblies, records sequence-point hits, restores the original assemblies, and writes coverage results. Drivers are available for Microsoft Testing Platform, the .NET global tool, VSTest, and MSBuild. The Microsoft Testing Platform driver can emit JSON, LCOV, OpenCover, and Cobertura reports. Depending on the driver, teams can merge reports, validate coverage thresholds, and support deterministic builds. Collector and MSBuild packages use VSTest; Microsoft Testing Platform projects instead use coverlet.MTP, which requires the .NET 8.0 SDK or newer. Cake.Coverlet and Visual Studio viewing extensions are also listed. Coverage gates are supported, and bugs or feature requests go through the repository issues section.
