• Not like that, lol

        Just saying, instead of this monstrosity

        CreateOrderRequest(user,
                           productDetails,
                           pricingCalculator,
                           order => order.internalNumber)
        

        Just use

        CreateOrderRequest(
            user,
            ...
        

        Putting the first argument on a separate line.

        Same if you have an if using a bunch of and (one condition per line, first one on a new line instead of same line as the if) and similar situations.
