Coverlet Free MIT licensed · supports modern .NET SDK-style projects github.com · 3 Oct 2026

Purpose: Coverlet is a cross-platform code coverage framework for .NET with line, branch and method coverage.
Coverage workflow: It instruments assemblies before tests run, records sequence point hits, restores the original assemblies and writes coverage results.
Drivers: Coverlet provides Microsoft Testing Platform, .NET global tool, VSTest and MSBuild integrations.
Feature options: Driver features include report merging, coverage threshold validation and deterministic build support, with availability varying by driver.
Test platform: The collector and MSBuild packages use VSTest and are incompatible with Microsoft Testing Platform; the project provides coverlet.MTP for MTP projects.
Requirements: Coverlet supports modern SDK-style projects, and its MTP package requires .NET 8.0 SDK or newer.
Integrations: The project lists a Cake.Coverlet add-in for Cake Build and extensions for viewing coverage in Visual Studio on Windows and Visual Studio for Mac.
Support: The project directs users to report bugs and feature requests through the repository’s issues section.
License: The repository states that Coverlet is licensed under the MIT License.
