SI.UnitOfWork.EntityFrameworkCore 2.1.0

SI.UnitOfWork

Introduction

Most of the repository pattern libraries for .NET or .NET Core depend on the Entity Framework. Unlike all these frameworks, the SI.UnitOfWork has no such dependencies and follows the strict paradigms of the repository pattern. But if you want, SI.UnitOfWork.EntityFrameworkCore provides a complete and ready-to-use library for SqLite, PostgreSQL, SQL Server and the InMemory provider of Entity Framework.

Getting Started with SI.UnitOfWork

1. Install and reference the NuGet package

Install-Package SI.UnitOfWork

2. Edit your ConfigureServices() method in Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // ..
    services.AddDbContext<IDbContext, SampleContext>(o => o.UseInMemoryDatabase("mem-db"));
    services.AddUnitOfWork<SampleContext>();
    services.AddScoped(typeof(IRepository<>), typeof(GenericRepository<>));
    services.AddScoped(typeof(ICustomRepository), typeof(CustomRepository));
    // ..
}

2. Inject and use

public class SampleClass
{   
    // Opt. 1. Inject a UoW for regular DB read and write operations
    // Opt. 2. Inject a UoW-Factory in case you work with multiple databases
    // Opt. 3. Inject a RepositoryFactory to get read-only repositories
    public SampleClass(
        IUnitOfWork unitOfWork, 
        IUnitOfWorkFactory<SampleContext> unitofWorkFactory,
        IRepositoryFactory<SampleContext> repositoryFactory)    
    {
        IRepository<Person> personRepository;   // Register generic repositories manually!
        ICustomRepository customRepository;     // Register custom repositories manually!


        // Opt. 1
        personRepository = unitOfWork.GetRepository<Person>();
        customRepository = unitOfWork.GetRepository<Person, ICustomRepository>();
        // .. do work
        unitOfWork.SaveChanges();


        // Opt. 2
        using var uow = unitofWorkFactory.GetUnitOfWork();
        personRepository = uow.GetRepository<Person>();
        customRepository = uow.GetRepository<Person, ICustomRepository>();
        // .. do work
        uow.SaveChanges();


        // Opt. 3
        personRepository = repositoryFactory.GetRepository<Person>();
        customRepository = repositoryFactory.GetRepository<Person, ICustomRepository>();
        // No SaveChanges available!
    }
}

Getting Started with SI.UnitOfWork.EntityFrameworkCore

1. Install and reference the NuGet package

Install-Package SI.UnitOfWork.EntityFrameworkCore

2. Edit your ConfigureServices() method in Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // ..
    services.AddDbContext<EFContext>(o => o.UseInMemoryDatabase("mem-db");
    services.AddEFUnitOfWork();
    services.AddScoped(typeof(ICustomRepository), typeof(CustomRepository));
    // ..
}

2. Inject and use

public class SampleClass
{
    public SampleClass(IUnitOfWork unitOfWork)
    {
        IRepository<Person> personRepository;   // Generic repositories are automatically registered!
        ICustomRepository customRepository;     // Register custom repositories manually!


        personRepository = unitOfWork.GetRepository<Person>();
        customRepository = unitOfWork.GetRepository<Person, ICustomRepository>();
        // .. do work
        unitOfWork.SaveChanges();
    }
}
