Release Notes: Version 10.0.1

Released on May 18, 2026. This release consolidates stability improvements, enhances Microsoft Testing Platform (MTP) logging compatibility, and patches minor edge-case instrumentations.

  • MTP Console Statistics: Resolved an issue where metrics were failing to print on standard outputs under the new Microsoft Testing Platform hooks.
  • Testhost Optimization: Avoided unnecessary testhost process restarts, reducing CI build execution latency.
  • Report Path Alignment: Corrected inconsistent absolute paths in Cobertura XML report outputs under windows architectures.
  • Pattern Matching Logic: Fixed a bug where branch coverage was under-calculated when utilizing the is pattern matching expressions combined with and operators.
  • Async Finally Blocks: Handled compiler generation anomalies that incorrectly flagged coverage percentages inside async method finally blocks.
  • Metadata Maintenance: Resolved missing CompilerGeneratedAttribute warnings in the coverlet tracker dll layers.

Download Frequently Asked Questions

Specific troubleshooting help regarding package installation and version setups.

How can I perform an offline installation?

You can download the raw NuGet package file (.nupkg) from the package listings on NuGet.org. Place this package inside a local folder and add it to your nuget.config file as a local package source, then run standard CLI commands pointing to your local source.

Are all the driver packages updated simultaneously?

Yes. The Coverlet repository follows a consolidated releases strategy. All driver packages (including MSBuild, Console, VSTest collector, and Microsoft Testing Platform adapters) share the same version numbers. This ensures clean dependency compatibility when referencing multiple drivers across large projects.

Which package driver should I choose?

For most modern .NET applications running inside standard visual studio test engines, the **coverlet.collector** package is recommended. Choose **coverlet.msbuild** if you need compilation variables validation, and use **coverlet.console** if you need to run coverage reports completely independently of your build configurations.
