Remarks

Users can use this to plug-in custom assertions through C# extension methods. For instance, the signature of a custom assertion provider could be "public static void ContainsWords(this StringAssert customAssert, string value, ICollection substrings)" Users could then use a syntax similar to the default assertions which in this case is "StringAssert.That.ContainsWords(value, substrings);" More documentation is at "https://github.com/Microsoft/testfx-docs".
