"Some of Linq features": is Any supported?

[JarboeJ]

I'm working to understand what I'm doing wrong with sequence operators. This documentation (https://microsoft.github.io/RulesEngine/) says "The lambda expression allows you to use most of C# constructs and along with some of linq features." Is "Any" supported? The behavior I'm getting is really strange. (I've been itereating on this dotnetfiddle, so it's improved, but I'm not able to demonstrate that Any or Where works.

Edit: to be more specific, i'm seeing a combination of two errors that don't make sense together for my input as far as I can understand:

input1.First().customer.serviceability.groups.Where(g => g.group == "B") - No property or field 'group' exists in type 'List`1'

Exception while parsing expression input1.First().customer.groups.Any("group == B") - No applicable method 'Any' exists in type 'Object'

If this is not supported, I would like to stop trying to make it work. :)

Hi @JarboeJ , There were some issues in the way input was sent. RulesEngine requires top level object to be passed as ExpandoObject(you are passing list of Object which will not work)

Here is a tweaked version of your sample code with where and any working - https://dotnetfiddle.net/KlRHYS

@abbasc52 I think I see it! Thank you for helping me correct my silly mistake.

Do you think a validation feature would be warranted to reject inputs like mine with a helpful error?

Thanks again, I'm very excited to put RulesEngine to work!
