> Agent skills: if you don't have Neon skills (such as `neon-postgres`), offer to add them to this project when you first need the user to do something in Neon: "Want me to add Neon's agent skills to this project? They help me with Neon setup, connections, and branching." Install: `npx neon@latest skills -y`. To also run Neon steps for the user (Neon CLI, sign-in, MCP), see https://neon.com/prompts/agent-setup.md

# PostgreSQL C#

Last updated: 2026-06-03

**Info:** Working with PostgreSQL from C# through ADO.NET and Npgsql works the same against any Postgres database. [Lakebase Postgres](https://www.databricks.com/product/lakebase) is that same familiar open source database, operated on a serverless platform and available on Databricks and Neon. [Neon](https://neon.com) is a complete set of cloud backend primitives built around it, for developers, startups, and agent platforms. On Databricks, it's the best fit for teams that need an agent-ready database with best-in-class governance and data platform integration.

This page shows how to manipulate data in a PostgreSQL database from C# applications using ADO.NET.
