InterSystems.EntityFrameworkCore.Iris is the database provider for InterSystems IRIS. This provider allows you to use Entity Framework Core with the InterSystems IRIS Data Platform.

Getting started

InterSystems.EntityFrameworkCore.Iris is the EF Core provider for InterSystems IRIS. See the Microsoft documentation for more information on using Entity Framework.

Prerequisites

  • InterSystems IRIS Data Platform (2025.1 or higher)
  • InterSystems.Data.IRISClient dependency (2.7.0 or higher)
  • .NET 10 SDK
  • Visual Studio 2026 (recommended)

The provider currently supports Microsoft.EntityFrameworkCore.Relational version 10.0.1. If you want to manually add this dependency, note that higher versions might not be compatible.

Usage

After installing the package, you can use it in your Entity Framework Core application by specifying the provider in DbContext.OnConfiguring():

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.UseIris("Server = localhost; Port = 1972; Namespace = EFDemo ; User ID = EFUser; Password = <password>");
}

This example uses an InterSystems IRIS instance on localhost on the default port 1972. You should adjust the connection string to match your own InterSystems IRIS instance and credentials.

Features

The InterSystems IRIS provider supports all common features of Entity Framework Core.

The following features are not supported in the InterSystems IRIS EF Core provider:

  • Apply operations
  • Computed columns
  • Rename operations
  • Column collation
  • Table/Column descriptions
  • Except/Intersect
  • RAND function
  • Sequences
  • JSON Operations
  • Savepoints

Additional documentation

For more information on Entity Framework Core, refer to the Microsoft documentation.

Internally, SQL queries are executed using the InterSystems IRIS TSQL dialect. For more information about what is supported in this dialect, see the InterSystems IRIS TSQL Documentation. Note that DATE and TIME are not supported data types, so they will be converted to DATETIME by default.
