PosInformatique.Foundations.MediaTypes.EntityFramework

Introduction

Provides Entity Framework Core integration for the MimeType value object from PosInformatique.Foundations.MediaTypes. This package enables seamless mapping of MIME types as strongly-typed properties in Entity Framework Core entities.

It ensures proper SQL type mapping, validation, and conversion to VARCHAR(128) when persisted to the database.

Install

You can install the package from NuGet:

dotnet add package PosInformatique.Foundations.MediaTypes.EntityFramework

This package depends on the base package PosInformatique.Foundations.MediaTypes.

Features

Provides an extension method IsMimeType() to configure EF Core properties for MimeType.
Maps to VARCHAR(128) database columns using the SQL type MimeType (you must define the SQL type MimeType mapped to VARCHAR(128) in your database).
Ensures validation and safe conversion to/from database fields.
Built on top of the core MimeType value object.

Use cases

Entity mapping: enforce strong typing for MIME types at the persistence layer.
Consistency: ensure the same rules are applied in your entities and database.
Safety: prevent invalid or malformed MIME type strings being stored in your database.

Examples

⚠️ To use IsMimeType(), you must first define the SQL type MimeType mapped to VARCHAR(128) in your database. For SQL Server, you can create it with:

CREATE TYPE MimeType FROM VARCHAR(128) NOT NULL;

Example: Configure an entity

using Microsoft.EntityFrameworkCore;
using PosInformatique.Foundations.MediaTypes;

public class Document
{
    public int Id { get; set; }

    public MimeType ContentType { get; set; }
}

public class ApplicationDbContext : DbContext
{
    public DbSet<Document> Documents => Set<Document>();

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Document>()
            .Property(d => d.ContentType)
            .IsMimeType();
    }
}

This will configure the ContentType property of the Document entity with:

VARCHAR(128) (non-unicode) column length
SQL column type MimeType
Proper conversion between MimeType and string
