Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.

MongoDB C# Driver Cheat Sheet

(C) 2015 by Derek Hunziker, (C) 2017 by AppsOn

As of releasing MongoDB 3.4 and C# Driver v2.4, original cheatsheet by Derek is outdated. In addition, it has some deficiencies like connecting to MongoDB, creating indexes, etc. This updated version works fine with C# Driver v2.4.7 and MongoDB v3.4.

Setup

Define Document Models

Note: Defined models and collections will be used in entire cheatsheet.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo since a gist is too difficult to maintain as an open source endevaor and there is no way to version it. I have updated below, but I will not be able to keep this one up to date so please checkout the repo instead. The below is just for some preservation for those who stumble across here.
