The PostgreSQL platform for .NET

Use one PostgreSQL-native stack for ADO.NET, EF Core, replication, real-time delivery, extensions, and graph. Start small, add only what you need, and verify every release through published evidence.

PLATFORM TOPOLOGYPOSTGRESQL-NATIVE DATA PLANE
BlueTusk architecture: .NET applications connect through Provider and EF Core to PostgreSQL. Streams then powers Sync, Live, and Continuous Graph while Control Plane observes the runtime. Sync delivers to Redis, NATS, and OpenSearch; Live delivers to applications.

11/11 live compatibility

Start with ADO.NET

Connect a .NET application, run a parameterized query, and use PostgreSQL types through familiar ADO.NET APIs.

THE ECOSYSTEM

Engineered for the modern PostgreSQL stack

Six product areas that work together.

Foundation

Provider

Connect .NET applications directly to PostgreSQL with familiar ADO.NET APIs.

1.1 RC public
Application model

EF Core

Use LINQ, migrations, and tooling without giving up PostgreSQL-specific features.

FAMILIAR .NET. NATIVE POSTGRESQL.

Start with a connection.
Keep every capability.

BlueTusk follows standard ADO.NET and EF Core patterns while exposing PostgreSQL features directly when your application needs them.

  • Typed parameters, never SQL interpolation
  • Async data paths and bounded resource use
  • Native COPY, replication, and type support
  • First-class diagnostics and release evidence
Program.cs
await using var dataSource =
    new BlueTuskDataSourceBuilder(connectionString).Build();

await using var command = dataSource.CreateCommand(
    "SELECT $1::int4 + $2::int4");

command.Parameters.Add(new BlueTuskParameter<int>(20));
command.Parameters.Add(new BlueTuskParameter<int>(22));

var answer = await command.ExecuteScalarAsync<int>();
POSTGRESQL, FULLY EXPOSED

The database stays powerful.

Types, schema objects, extensions, and SQL features stay first class across the provider and EF Core.

1.1 RC RELEASE EVIDENCE · 29 AUG 2026

Published, verified, and explicit about the boundary.

All 65 RC packages are public and clean consumer smoke passed. Stable 1.1 remains deliberately blocked on the exact stable-candidate programme, including endurance and PostgreSQL 19 GA.
