This is big in functional programming. const - For creating constants. Conceptually, the biggest difference between the two is:

However, the difference is so minuscule that I can't see it making any difference. Also, that's the trade off of using one or another, optimization vs flexibility.

I like getting the recommendation, as it makes your code as strict and clear as possible. If you use ReSharper, it will tell you when fields can be marked as read-only.
