Thanks to your feedback - SqlCommandFilters has been improved!

Thanks to reader EricEJ I have added an extension method to SqlCommandFilters which means instead of coding the call like this

// Explicit usage
//SqlCommandFilters.Parameters.Parameterize(ref cmd);

you can now call it like this

// Extension method on SqlCommand
cmd.Parameterize(false);

To do so requires two changes to the Parameters class

first you need to modify the class definition to be static

//was public class Parameters

public static class Parameters

And then you need to add the extension method itself.

public static void Parameterize(this SqlCommand cmd, bool reparse = true)
{
Parameterize(ref cmd, reparse);
}

And just like that SqlCommandFilters is now an extension method on SqlCommand class!

I will be checking in the change (and the change to the test app) to GitHub when I get back from family holiday.
