  To integrate a separate DDD module with the host application while utilizing a shared database context in ABP Framework, you should implement the following approach:

  1. Implement Shared DbContext Interface
     Define a common interface that both the host application and the module can implement for the shared entities.

  public interface ISharedDbContext : IEfCoreDbContext
     {
         DbSet<YourEntity> YourEntities { get; set; }
         // Add other shared DbSets here
     }
  

  2. Module DbContext Implements Shared Interface
     In your module, have the module's DbContext implement the shared interface.

  public class ModuleDbContext : AbpDbContext<ModuleDbContext>, ISharedDbContext
     {
         public DbSet<YourEntity> YourEntities { get; set; }
         // Other module-specific DbSets
     }
  

  3. Host Application DbContext Implements Shared Interface
     In the host application, have the main DbContext also implement the shared interface and include the module's entities.

  public class HostDbContext : AbpDbContext<HostDbContext>, ISharedDbContext
     {
         public DbSet<YourEntity> YourEntities { get; set; }
         // Other host-specific DbSets
     }
  

  4. Register Repositories for Shared Entities
     In the host application, register the repository for the module's entities using the host application's DbContext.

  context.Services.AddAbpDbContext<HostDbContext>(options =>
     {
         options.AddDefaultRepositories(includeAllEntities: true);
         options.AddRepository<YourEntity, YourEntityRepository>();
     });
  

  5. Use the Host DbContext for Both Host and Module
     When running in the host application, ensure that the module uses the host application's DbContext for all operations. This allows both the host and the module to work with the same database context and tables.

  6. Dependency Injection
     Inject the repository or DbContext as needed in your application or module services.

  public class YourAppService : ApplicationService
     {
         private readonly IRepository<YourEntity, Guid> _yourEntityRepository;
  
         public YourAppService(IRepository<YourEntity, Guid> yourEntityRepository)
         {
             _yourEntityRepository = yourEntityRepository;
         }
  
         // Use _yourEntityRepository for CRUD operations
     }
  

  This approach ensures that both the host application and the module operate on the same database context and tables, maintaining consistency and enabling seamless integration.

  The error is Cannot resolve parameter 'Gaming.FortniteApi._MyStructure.IFortniteItemCacheRepository cacheRepository

  Can you share your project source code instead of screenshots?

  hi

  The IFortniteItemCacheRepository doesn't have an implementation.

  See https://github.com/abpframework/abp/blob/dev/modules/identity/src/Volo.Abp.Identity.EntityFrameworkCore/Volo/Abp/Identity/EntityFrameworkCore/EfCoreIdentityUserRepository.cs#L16-L22
