EFCommenter

All summaries of entities, properties, and enums will be added as comments on the corresponding database tables and columns.

---

Features

• Automatically adds table comments from entity class summaries.
• Adds column comments from property summaries.
• Supports enum types as column comments.
• Works with SQL Server and PostgreSQL.
• Easy to integrate into your EF Core project using a single extension method.

---

Installation

dotnet add package EFCommenter

---

Usage

Enable XML documentation in your project by adding this to your .csproj:

<PropertyGroup>
    <GenerateDocumentationFile>true</GenerateDocumentationFile>
</PropertyGroup>

Then, call the extension method in your DbContext:

using EFCommenter;
using Microsoft.EntityFrameworkCore;

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.AddEntitiesComments();
}

---

Example

Your entities and enums include some comments.

/// <summary>
/// The class declered a person!!!
/// </summary>
public class Person
{
    public int Id { get; set; }

    /// <summary>
    /// The full name of the person!!!
    /// </summary>
    public string Name { get; set; } = "";

    public PersonType Type { get; set; }
}

public enum PersonType
{
    Admin,
    User,
    Guest
}

In the migration adding, the summaries will be automatically added as table and column comments in the created migration file, and they are ready to update the database comments.

migrationBuilder.CreateTable(
    name: "People",
    columns: table => new
    {
        Id = table.Column<int>(type: "int", nullable: false)
            .Annotation("SqlServer:Identity", "1, 1"),
        Name = table.Column<string>(type: "nvarchar(max)", nullable: false, comment: "The full name of the person!!!"),
        Type = table.Column<int>(type: "int", nullable: false, comment: "0: Admin | \n1: User | \n2: Guest | ")
    },
    constraints: table =>
    {
        table.PrimaryKey("PK_People", x => x.Id);
    },
    comment: "The class declered a person!!!");

Notes

• Make sure your EF Core project targets .NET 8 or later.
• XML documentation file must be enabled for the summaries to be read.
• Tested with PostgreSQL and SQL Server.
