Setup EF Core event store

1. Install NuGet package JKang.EventSourcing.Persistence.EfCore

   PM> Install-Package JKang.EventSourcing.Persistence.EfCore

2. According to your requirement, select database engine and install corresponding NuGet package. For example Microsoft.EntityFrameworkCore.InMemory

   PM> Install-Package Microsoft.EntityFrameworkCore.InMemory

3. Create the DbContext containing the table for storing events

       public class SampleDbContext : DbContext,
           IEventDbContext<GiftCard, Guid>
       {
           public SampleDbContext(DbContextOptions<SampleDbContext> options)
               : base(options)
           { }
   
           public DbSet<EventEntity<Guid>> GiftCardEvents { get; set; }
   
           protected override void OnModelCreating(ModelBuilder modelBuilder)
           {
               modelBuilder.ApplyConfiguration(new EventEntityConfiguration<Guid>());
           }
   
           DbSet<EventEntity<Guid>> IEventDbContext<GiftCard, Guid>.GetEventDbSet() => GiftCardEvents;
       }

4. Register event sourcing services in ConfigureServices()

   services
       .AddDbContext<SampleDbContext>(x => x.UseInMemoryDatabase("local"));
   
   services
       .AddEventSourcing(builder =>
       {
           builder
               .UseEfCoreEventStore<SampleDbContext, GiftCard, Guid>();
       });
