Chakra.Core.EntityFramework 5.0.2

Chakra.Core.EntityFramework

Provider for Microsoft EntityFramework Core in Chakra.Core framework

Please checkout README.md on "Chakra.Core" package, first... Then:

1. Define your own DbContext implementation like that:

public class ApplicationDbContext: DbContext
{
    public DbSet<Product> Products { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        //TODO...Insert here configuration
    }
}

2. Implement a concrete class for a storage provider on Entity Framework Core

[Repository]
public class EntityFrameworkProductRepository: EntityFrameworkRepositoryBase<Product, ApplicationDbContext>, IProductRepository
{
    public EntityFrameworkProductRepository(IDataSession dataSession) 
        : base(dataSession, dbcontext => dbcontext.Products) { }

    public IList<Product> FetchAvailableProductsInPeriod(DateTime from, DateTime to) 
    {
        //TODO...Insert here the method implementation
		//ex: => DataSession.Context.Products.Where(p => ...
    }
}

3. Register default data session for application

SessionFactory.RegisterDefaultSession<EntityFrameworkDataSession<ApplicationDbContext>>();

4. Open session on storage (ex. database) using default configured provider, resolve repository interface using registered storage provider and obtain concrete repository implementation

using (IDataSession dataSession = SessionFactory.OpenSession())
{
    var productRepository = dataSession.ResolveRepository<IProductRepository>();

    var entities = productRepository.FetchAvailableProductsInPeriod(
        new DateTime(2013, 8, 1), DateTime.Now);
}

You have the opportunity to switch a provider (ex. from fake to Entity Framework, from NHibernate to MongoDb) changing a single line of code on your application that can be really database agnostic and every single part can be tested in its own isolated context.
