autocontext.entityframeworkcore's Introduction

AutoContext

AutoContext.EntityFrameworkCore is a lightweight extension of Entity Framework Core for entity to entity configuration mapping.

How to build

AutoContext.EntityFrameworkCore is built against the latest ASP.NET Core 3.

Install the latest .NET Core 3.x SDK
Run build.ps1 in the root of the repo

Getting Started

Install nuget package to a new or existing project

Install-Package AutoContext.EntityFrameworkCore

Define your entities

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

Define your context

public class YourContext : AutoContextBase
{
    public YourContext(DbContextOptions options) 
      : base(options)
    {
    }
}

// or for context without inheritance from AutoContext
public class YourContextWithoutInheritanceFromAutoContext : DbContext
{
    public YourContextWithoutInheritance(DbContextOptions options) 
      : base(options)
    {
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        Database.ApplyConfigurations(modelBuilder);

        base.OnModelCreating(modelBuilder);
    }
}

Define your mapping configurations in any assembly

[MappingConfiguration(contextType: typeof(YourContext))]
public abstract class YourBaseMapping<TEntity> : AbstractEntityTypeConfiguration<TEntity> 
  where TEntity : class
{
}

public class YourCustomEntityMapping : YourBaseMapping<YourEntity>
{
    public virtual void Configure(EntityTypeBuilder<TEntity> builder)
    {
      // Your configuration here
    }
}

services.AddDbContext<YourContext>(options =>
{
    // other registrations
    
    // If the mapping assembly name is null then will be used assembly of YourContext.
    options.UseMappingAssembly();
    // or
    options.UseMappingAssembly(<yourMappingAssemblyName>);
});
