Repository

EntityFramework Core repository

Description

Implementing abstraction of repositories using EntityFramework Core for access to data store.

Registration and configuration of entities context can occur from the RegisterContext<TDbContext>(dbContextOptionsBuilder => {}, entitiesBuilder => {}) method.

Install

For use you needed install packages:

Install-Package Skidbladnir.Repository.EntityFrameworkCore

Using

Preparation

Sample entity:

    public class SimpleMessage : IHasId<int>
    {
        public int Id { get; set; }
        public string Text { get; set; }
        public DateTime? Timestamp { get; set; }
    }

Sample entity map:

    public class SimpleMessageConfiguration : IEntityTypeConfiguration<SimpleMessage>
    {
        public void Configure(EntityTypeBuilder<SimpleMessage> builder)
        {
            builder.ToTable("MessageStore");
        }
    }

Sample DbContext (implements DbContextBase):

    public class SampleDbContext : DbContextBase
    {
        public SampleDbContext(DbContextOptions<SampleDbContext> options) : base(options)
        {
        }

        public DbSet<SimpleMessage> Messages { get; set; }
        public DbSet<SimpleGuid> Guids { get; set; }
    }

Registration

Next, we register our DbContext, entity and its configuration. We use sqlite as a database.
Register theirs in ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
    services.RegisterContext<SampleDbContext>(
        builder => builder.UseSqlite("Data Source=sample.db;Cache=Shared"),
        entities =>
        {
            entities.AddEntity<SimpleMessage, SimpleMessageConfiguration>();
        }
    );
}
