    Please be more specific about your error. When do you get "not found"? Is this a compiler error or when you run your code? Since it seems code related then please post the code that isn't working.

    The method in question has been around a long time and the following simplistic example shows how to use it.

    var dir = new DirectoryInfo(@"C:\temp");
    var files = dir.GetFiles("*.txt", new EnumerationOptions() { MaxRecursionDepth = 2 });
    foreach (var  file in files)

    Note that if you're using .NET Standard 2.0 then you also need a using System.IO in your file.
