Version 2 of my open source feature toggling .Net library has just been released to NuGet.
V2 introduces a number of breaking changes – see release notes. It also include binary Windows Store DLLs as opposed to code-only.
Version 2 will form the base for new feature in the future.
FeatureToggle.Core has been introduced as a portable class library.
For more details see the documentation, or the examples.
