-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.
