The other day I ran into a usage of the null conditional operator (added in C# 6) that made me realize that we can get our terseness on in some additional situations.
Instead of having to do a thing like this to ensure no nulls:
var thing = someParameter != null && someProperty.subProperty != null && someSubProperty.subPropCollection != null ? someParameter.subProperty.subPropCollection : new List<string>();
We can just do it like this:
var thing = someProperty?.subProperty?.subPropCollection ?? new List<string>();
Go forth and do good with this newfound information!
