Npgsql

Npgsql is a database driver for .NET that enables application developers to interact with PostgreSQL databases from their C# or VB.NET code. It is developed and maintained by EnterpriseDB, a leading provider of enterprise-class PostgreSQL products and services.

The current version of Npgsql is 4.1.5, which provides excellent compatibility with PostgreSQL 9.0 and up, as well as support for various advanced features such as SSL, replication, and server-side prepared statements.

• SSL - Secure Sockets Layer (SSL) is a security protocol that encrypts communication between the client and the database server.
• Replication - Replication allows for the creation of standby servers that can be used for failover, backup, or read-only access.
• Server-side prepared statements - Prepared statements are a performance enhancement technique that allows queries to be precompiled on the server side and executed multiple times with different parameter values.

Npgsql is an open source project that is available on GitHub under the MIT license. It has a vibrant community of contributors and users who are actively engaged in its development and support.

Npgsql provides a robust and feature-rich way for .NET developers to work with PostgreSQL databases in their applications.
