MockFileSystem consistency issue with slash/backslash paths on Windows

[EmilianoElMariachi]

MockFileSystem is not consistent under Windows.

var fs = new MockFileSystem();
fs.AddFile(@"c:\d1\d2\file.txt", new MockFileData("Hello"));

Console.WriteLine(fs.Directory.GetFiles("c:/d1/d2/").Length); // Prints "0": not correct
Console.WriteLine(fs.File.Exists("c:/d1/d2/file.txt")); // Prints "true": correct but not consistent with GetFiles

Under Windows, directory paths are considered equals whatever they are written with slashes of backslashes.

Was working fine in 2.0.
