The record

Purpose: Measures what proportion of a project's code is exercised by coded tests such as unit tests.
Managed and native code: Coverage analysis supports managed CLR code and unmanaged native code; native coverage is disabled by default in the MTP extension.
Instrumentation: The tooling supports static and dynamic instrumentation.
Test frameworks: With Microsoft.Testing.Platform.MSBuild, coverage extensions are auto-registered when installed with MSTest, NUnit, and xUnit runners.
Usage: The repository documents collecting coverage for .NET tests with dotnet test and for other .NET applications with the dotnet-coverage tool.
Configuration: Coverage settings can control output, inclusion and exclusion rules, and instrumentation options using runsettings or dedicated coverage settings files.
Operating systems: The supported operating systems include Windows, macOS, and multiple Linux distributions, with instrumentation support varying by OS, version, and architecture.
Platform limits: Other operating systems are supported on a best-effort basis, and some OS and architecture combinations support static instrumentation only.
Runtime dependency: Dynamic instrumentation on macOS and Linux requires the libxml2 package; missing required dependencies may cause an empty coverage report.
Test assembly default: MTP excludes test assemblies from coverage by default unless configured otherwise.
Security: The repository links to a security policy, but its README describes this repository as documentation and samples for closed-source coverage functionality.
Support: The repository invites users to report issues related to the Microsoft.CodeCoverage and dotnet-coverage NuGet packages and Visual Studio code coverage functionality.
Intended users: The documented workflows cover .NET test projects and other .NET applications that users want to measure for code coverage.
