By default, PowerArgs is case insensitive, but there is a way to change it. Can you try to put the [ArgIgnoreCase(false)] attribute on your class and see if that helps? That will force all of your usage to be case sensitive.
It might actually have been a bug that it worked before. I would have expected you to get an InvalidArgDefinitionException, but it looks like my verification code doesn't check for shortcuts that are the same when you ignore case.

After more investigation, I am sure about this. Your code should have never worked without that attribute. -p and -P are the same. I've already coded a fix that will throw an InvalidArgDefinitionException in this case for my next check in. I'll leave this issue open until then.
Let me know if you have any more questions or suggestions on this issue.

So my first paramater is called Path with arg position of 0 I don't want it to have a shortcut and then I have a parameter called Pattern this is set to shortcut to P. When I add the attribute I get
Duplicate arg options with shortcut P
Is this expected behaviour?

You have a few options here.
1 You can add [ArgShortcut(null)] to a property which will mean it has no shortcut.
2 You can specify a shortcut like [ArgShortcut("pa")] for one and [ArgShortcut("p")] for the other to avoid the conflict.
3 You can remove the ArgShortcut attributes altogether and let PowerArgs come up with defaults that don't conflict (in this case it will choose "p" for the first property it finds and "pa" for the second).

Thanks mate :)

No problem. This is inspiring me to make sure I flag more of these potential issues in my validation code. Thanks for reporting it.

Another thought I had was rather than having ArgShortcut and pass null. Maybe have a class called ArgNoShortcut as I personally hate passing in null. This makes it more explicit.
from powerargs.
I'm not a huge fan of adding additional surface area where it's not needed. What about a middle ground. ArgShortcut could have a constant defined called ArgShortcut.NoShortcut. You could then pass that to the ArgShortcut attribute. It would be as explicit as the ArgNoShortcut class without adding a new type.
from powerargs.
I'm happy with that just thought it would be less typing with a new type. So the class now would take either an enum or a string?
from powerargs.
Yup. I'm thinking something like [ArgShortcut(ShortcutPolicy.NoShortcut)].

Awesome looking forward to it :)

It's in. ArgShortcutPolicy.NoShortcut,
