Entity, Framework, EF, Core, Data, O/RM, entity-framework-core,Oracle

Df.EntityFrameworkCore.Oracle is an Entity Framework Core provider built on top of Oracle.ManagedDataAccess.Core. It allows us to use the Entity Framework Core ORM with Oracle. Async functions in this library properly implement Async I/O at the lowest level.

Getting Started

Here is a console application sample for accessing a Oracle database using Entity Framework:

② Put Df.EntityFrameworkCore.Oracle into your project's .csproj file

<Project Sdk="Microsoft.NET.Sdk">


	<PackageReference Include="Df.EntityFrameworkCore.Oracle" Version="1.0.0" />

③ Implement some models, DbContext in Program.cs. Then overriding the OnConfiguring of DbContext to use Oracle database. Besides. Finally to invoking Oracle with EF Core in your Main() method.

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using Microsoft.EntityFrameworkCore;

namespace OracleTest
    public class User
        public int UserId { get; set; }

        public string Name { get; set; }

    public class Blog
        public Guid Id { get; set; }

        public string Title { get; set; }

        public int UserId { get; set; }

        public virtual User User { get; set; }

        public string Content { get; set; }


    public class MyContext : DbContext
        public DbSet<Blog> Blogs { get; set; }

        public DbSet<User> Users { get; set; }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
            => optionsBuilder
                .UseOracle(@"DATA SOURCE=;PASSWORD=test;PERSIST SECURITY INFO=True;USER ID=test;");

    public class Program
        public static void Main()
            using (var context = new MyContext())
                // Create database

                // Init sample data
                var user = new User { Name = "Yuuko" };
                var blog1 = new Blog {
                    Title = "Title #1",
                    UserId = user.UserId,
                    Tags = new List<string>() { "ASP.NET Core", "Oracle", "Df" }
                var blog2 = new Blog
                    Title = "Title #2",
                    UserId = user.UserId,
                    Tags = new List<string>() { "ASP.NET Core", "Oracle" }



                // Output data
                var ret = context.Blogs
                    .Where(x => x.Tags.Object.Contains("Df"))
                foreach (var x in ret)
                    Console.WriteLine($"{ x.Id } { x.Title }");
