ADO.NET provider and native bindings for DuckDB, enabling C# applications to interact with the in-process analytical database.
DuckDB.NET is the official .NET data provider and native binding library for DuckDB, an in-process analytical database. It enables C# and .NET applications to execute SQL queries, manage database connections, and interact with DuckDB databases using standard ADO.NET interfaces. The library solves the problem of integrating DuckDB's high-performance analytical engine into .NET-based data processing pipelines and applications.
.NET developers and data engineers who need to incorporate analytical database capabilities into their C# applications, particularly those working with data-intensive workloads, embedded analytics, or local data processing.
Developers choose DuckDB.NET because it provides the official, fully-featured .NET integration for DuckDB with both high-level ADO.NET compatibility and low-level native bindings. It offers reliable performance, active maintenance, and seamless integration with the broader DuckDB ecosystem including MotherDuck.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements standard System.Data interfaces like DbConnection and DbCommand, allowing .NET developers to reuse existing database code patterns with minimal changes, as shown in the usage example.
Provides low-level C# bindings to DuckDB's C API for advanced use cases, enabling performance tuning and extension development, as highlighted in the key features.
Includes built-in support for MotherDuck with simple connection string syntax, facilitating seamless migration to cloud-hosted analytical databases without extra configuration.
Offers multiple NuGet package variants including 'Data' and 'Bindings' in standard and 'Full' statically linked distributions, catering to different deployment and dependency management needs.
Known to cause System.AccessViolationException during debugging due to interaction with native memory, requiring workarounds like adjusting IDE settings, as noted in the README's known issues.
Relies on DuckDB's native libraries, which can complicate cross-platform deployment, increase binary size, and introduce potential compatibility headaches.
Focuses on ADO.NET without built-in higher-level abstractions like an ORM, necessitating more boilerplate code for object-relational mapping and data handling.
