Adoption guide
Applications standardized on PostgreSQL that need robust async support and observability integration.
Why it appears in the guide: High-quality PostgreSQL data provider for .NET with strong performance and PostgreSQL feature coverage. Trade-off: Provider-specific data type behaviors should be tested when porting from other engines.
Compatibility metadata lists 2 target frameworks; confirm the exact target used by your application.
How to read this guidance
Sources: published NuGet v3 registry metadata and explicit NuBrowse editorial guides. Refresh: package metadata is refreshed from NuGet when the page loads. Limit: this is not a security, legal or compatibility guarantee; validate the selected version in your project.
