dotnet/reactive

This system is a .NET library providing asynchronous extensions for LINQ and Reactive programming. It implements `IAsyncEnumerable`-based operators for both queryable and enumerable data streams, alongside a comprehensive Reactive Extensions (Rx) implementation featuring async observables, schedulers, and disposable management. The codebase includes tooling for API comparison and performance benchmarking, while maintaining backward compatibility through deprecation facades and extensive xUnit test coverage.

This period focused on modernizing the build infrastructure and expanding cross-platform test coverage for the Interactive Extensions library. Key changes included removing legacy async LINQ implementations, restructuring the project with modern .NET tooling, and adding integration tests for a wide range of .NET platforms and frameworks.

This period focused on modernizing the codebase by migrating the test suite to xUnit and refactoring async LINQ operators to use ValueTask and cancellation tokens for improved performance. The work also involved reorganizing the code structure into individual files, adding new operators like MaxByWithTies, and introducing tooling to compare synchronous and asynchronous APIs.

26 changes

This period focused on introducing comprehensive async support for Reactive Extensions and enhancing LINQ performance measurement. The codebase expanded with new async types, schedulers, and disposable patterns, while simultaneously refactoring source generators and updating API approvals to reflect modernized, backward-compatible interfaces.

dotnet/reactive was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
