The extension provides new behaviour for Cosmos DB triggers, input bindings, and output bindings. It is built upon the Cosmos DB v3 SDK and includes performance benefits, support for identity-based connections, and newer types for .NET functions.

At the time of this initial announcement, the use of identity-based connections for CosmosDBTrigger is limited to Elastic Premium and dedicated plans. Support for Consumption plans will be added in a future service update.

The preview version is available on NuGet. If you encounter any problems, please file an issue on the GitHub repo.

Learn more about the changes from the Cosmos DB extension documentation.
