## What it is
Npgsql.EntityFrameworkCore.PostgreSQL is the official Entity Framework Core provider for PostgreSQL, built on top of the Npgsql ADO.NET driver. It lets .NET developers query and persist PostgreSQL data using LINQ and exposes PostgreSQL-specific features like JSON, array, and range columns.

## Use cases
- use entity framework core with postgresql in .net
- query postgres json and array columns via linq
- map .net entities to postgresql tables
- use linq instead of raw sql for postgres queries
- add postgis spatial support to ef core
- use nodatime date types with postgresql

## When to choose
- you're building a .NET application with PostgreSQL and want an ORM
- you need LINQ-based querying with PostgreSQL-specific column types
- you want the standard, well-supported EF Core provider for Postgres

## When to avoid
- you use a database other than PostgreSQL
- you need raw SQL control or a lightweight micro-ORM like Dapper
- you're not on the .NET platform

## Facets
- artifact type: library
- maturity: stable
- function: orm, database-driver, database
- domain: databases, backend, web-development
- platform: dotnet, cross-platform
- tags: postgresql, entity-framework-core, linq, npgsql, csharp
