.NET Driver 2.17.0 Released

.NET Driver Version 2.17.0 Release Notes

This is the general availability release for the 2.17.0 version of the driver.

The main new features in 2.17.0 include:

  • Support for MongoDB server version 6.0.0 GA
  • [BETA] Support for Queryable Encryption
  • LINQ3 bug fixes and improvements
  • Add arbitrary aggregation stages to LINQ queries using IMongoQueryable.AppendStage() method (LINQ3)
  • Support for $topN and related accumulators in $group aggregation stage

EstimatedDocumentCount and Stable API

EstimatedDocumentCount is implemented using the count server command. Due to an oversight in versions 5.0.0-5.0.8 of MongoDB, the count command, which EstimatedDocumentCount uses in its implementation, was not included in v1 of the Stable API. If you are using the Stable API with EstimatedDocumentCount, you must upgrade to server version 5.0.9+ or set strict: false when configuring ServerApi to avoid encountering errors.

For more information about the Stable API see:
