Getting Started

A library for implementing generic repositories and unit of work with Entity Framework Core. This implementation uses a single instance of the DbContext for all repositories to avoid concurrency issues.

Installation

Using the NuGet package manager console within Visual Studio run the following command:

Install-Package Ortix.RepositoryPattern.EntityFrameworkCore

Or using the .NET Core CLI from a terminal window:

dotnet add package Qrtix.RepositoryPattern.EntityFrameworkCore

Creating the DbContext

Create your DbContext inheriting from Microsoft.EntityFrameworkCore.DbContext:

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

    protected override void OnModelCreating(ModelBuilder modelBuilder)
	{
		modelBuilder.ApplyConfigurationsFromAssembly(Assembly.GetExecutingAssembly());
		base.OnModelCreating(modelBuilder);
	}
}

Configure your DbContext in the Program class:

builder.Services.AddDbContext<DbContext, SuinQShopModuleDbContext>(opt =>
    {
        opt.UseSqlServer(builder.Configuration.GetConnectionString("ConnectionString"));
    });

Injecting the RepositoryPattern's Services

Add the RepositoryPattern services to the Service Collection:

builder.Services.AddRepositoryPattern(options => {
    options.UseEntityFrameworkCore();
});

The default scope for injected services is scoped. If you want to change it, refer to the next examples:

Using the same lifetime:

builder.Services.AddRepositoryPattern(options => {
    options.UseEntityFrameworCore(ServiceLifetime.Singleton);
});

Using individual lifetime:

builder.Services.AddRepositoryPattern(options => {
    options.UseEntityFrameworCore(ServiceLifetime.Scoped, SeriviceLifetime.Singleton);
});
