Productionalize approach for MongoDB

I have gone through some of the interesting C# corner articles written over MongoDB.

Though I have some doubts over how to use Mongo in a Production environment with C# code base.

My intention is to understand what possible options in terms of query storing/execution, results validation, a developer have while working with MONGO.

Lets say in case of SQL we have SP's which we execute using JS. What can be done in case of MONGO.

I have gone through system.js collection docs but Mongo itself doesn't recommend that for usage. :(

All ideas and inputs are appreciated.

Thanks
