A C# library that allows classes to implement interfaces implicitly. Allows for any class to implement any interface as long as the class has the same method and/or property signature.


using Implicitify;

public interface IDirectoryInfo
    string Name { get; }

public static class Program
    public static void Main()
        // DirectoryInfo is a System.IO class, it does not implement
        // any interface, however, it would be nice to abstract it.
        var directory = new System.IO.DirectoryInfo(@"C:\Hello World\");

        // Wrapped is an IDirectoryInfo implementation!
        var wrapped = directory.As<IDirectoryInfo>();

        // Will "Hello World"


When adding abstractions on top of well-known C# classes such as FileInfo, HttpClient or even any external nuget that one may wish to extend. There's always the complicated extra step of having to create an interface for these types that add the methods and then creating a Wrapper. However this is too much work, although it guarantees type-safety.


In languages such as Go interfaces are always implemented implicitly, this allows for greater abstractions that the implementations aren't aware of. However in both C# and Java this isn't a feature.
