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
  ```csharp
  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
```csharp
[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
    }
}

• Register your context

  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>);
  });
