AWS Advanced .NET Data Provider Driver Release

The AWS Advanced .NET Data Provider Driver is now available for Amazon RDS and Amazon Aurora PostgreSQL and MySQL-compatible databases. This driver improves application availability by reducing switchover and failover times. It supports multiple authentication mechanisms, including Federated Authentication, AWS Secrets Manager authentication, and token-based authentication with AWS IAM.

The driver builds on top of Npgsql PostgreSQL, native MySql.Data, and MySqlConnector drivers, offering enhanced functionality. It is natively integrated with Aurora and RDS databases, enabling it to monitor cluster status and quickly connect to new writers during failovers. It also works with popular frameworks like NHibernate and supports Entity Framework (EF) with MySQL databases.

The driver is available as an open-source project under the Apache 2.0 license. For more information, refer to the GitHub repository.
