-.NET feature management library provides a way to develop and expose application functionality based on features flags. Once a new feature is developed, many applications have special requirements, such as when the feature should be enabled and under what conditions. This library provides a way to define these relationships, and also integrates into common .NET code patterns to make exposing these features possible.

This library provides a way to define these relationships, and also integrates into common .NET code patterns to make exposing these features possible.
 
 Feature flags provide a way for .NET and ASP.NET Core applications to turn features on or off dynamically. Developers can use feature flags in simple use cases like conditional statements to more advanced scenarios like conditionally adding routes or MVC filters. Feature flags are built on top of the .NET Core configuration system. Any .NET Core configuration provider is capable of acting as the backbone for feature flags.
