Thanks to reader EricEJ I have added an extension method to SqlCommandFilters which means instead of coding the call like this
// Explicit usage
// you can now call it like this
// Extension method on SqlCommand
// 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.
