DotNetCore.EntityFrameworkCore.GaussDB is the open source EF Core provider for PostgreSQL. It allows you to interact with PostgreSQL via the most widely-used .NET O/RM from Microsoft, and use familiar LINQ syntax to express queries. It's built on top of [DotNetCore.GaussDB](https://github.com/dotnetcore/DotNetCore.GaussDB).

The provider looks and feels just like any other Entity Framework Core provider. Here's a quick sample to get you started:

```csharp

await using var ctx = new BlogContext();

await ctx.Database.EnsureDeletedAsync();

await ctx.Database.EnsureCreatedAsync();

// Insert a Blog

ctx.Blogs.Add(new() { Name = "FooBlog" });

await ctx.SaveChangesAsync();

// Query all blogs who's name starts with F

var fBlogs = await ctx.Blogs.Where(b => b.Name.StartsWith("F")).ToListAsync();

public class BlogContext : DbContext

{

    public DbSet Blogs { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

        => optionsBuilder.UseGaussDB(@"host={host};port={port};username={username};password={password};database={database}");

}

public class Blog

{

    public int Id { get; set; }

    public string Name { get; set; }

}

```
