Write aggregation pipelines in LINQ

Transform and process your data with MongoDB’s modular, multi-stage aggregation framework. Easily customize and configure your data analysis using familiar LINQ expressions and syntax.

LINQ

Programmatically encrypt key data

Add an extra layer of security with client-side field level encryption (CSFLE). Enable CSFLE on the MongoClient and encrypt fields with a JSON schema, so sensitive data is never transmitted unencrypted nor seen unencrypted by the MongoDB server.
