  Hi,

  I think it's better to share the project with you, so you can test easier and for sure spot the problem quickier

  Well, not so easier, but ok.

  I've create the following files in the following projects/folders:

  • Project.Domain

    • TicketStatuses

      • ITicketStatusRepository.cs

      • TicketStatus.cs

      • TicketStatusAlreadyExistsException.cs

      • TicketStatusManager.cs

  • Project.Domain.Shared

    • TicketStatuses

      • TicketStatusConsts.cs

  • Project.EntityFrameworkCore

    • EfCoreTicketStatusRepository.cs

  • Project.Application

    • TicketStatuses

      • TicketStatusesAppService.cs

  • Project.Application.Contracts

    • TicketStatuses

      • CreateTicketStatusDto.cs

      • ITicketStatusAppService.cs

      • TicketStatusDto.cs

      • UpdateTicketStatusDto.cs

  In Project.Application on file ProjectApplicationAutoMapperProfile.cs I've added

  CreateMap<TicketStatus, TicketStatusDto>()

  In Project.EntityFrameworkCore -> EntityFrameworkCore
  - IndoDbContext.cs
  - public DbSet<TicketStatus> TicketStatuses { get; set; }

  • IndoDbContextModelCreatingExtensions
    builder.Entity<TicketStatus>(b =>
    {
    b.ToTable(IndoConsts.DbTablePrefix + "TicketStatuses", IndoConsts.DbSchema);
    b.ConfigureByConvention();
    b.Property(x => x.Description).HasColumnName(nameof(TicketStatus.Description)).IsRequired();
    b.Property(x => x.CloseTicket).HasColumnName(nameof(TicketStatus.CloseTicket));
    });

    Project is compiling without any error.

    The I went to the command shell, Project.EntityFrameworkCore, and done the following command

    dotnet ef migrations add Added_TicketStatuses

  hi

  There is should be a IndoDbContextFactory.cs file and Microsoft.EntityFrameworkCore.Tools package in hte EntityFrameworkCore project.

  /* This class is needed for EF Core console commands
   * (like Add-Migration and Update-Database commands) */
  public class IndoDbContextFactory : IDesignTimeDbContextFactory<IndoDbContext>
  {
      public IndoDbContext CreateDbContext(string[] args)
      {
          IndoEfCoreEntityExtensionMappings.Configure();
  
          var configuration = BuildConfiguration();
  
          var builder = new DbContextOptionsBuilder<IndoDbContext>()
              .UseSqlServer(configuration.GetConnectionString("Default"));
  
          return new IndoDbContext(builder.Options);
      }
  
      private static IConfigurationRoot BuildConfiguration()
      {
          var builder = new ConfigurationBuilder()
              .SetBasePath(Path.Combine(Directory.GetCurrentDirectory(), "../Indo.DbMigrator/"))
              .AddJsonFile("appsettings.json", optional: false);
  
          return builder.Build();
      }
  }
  

  <ItemGroup>
      <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="5.0.*">
        <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
        <PrivateAssets>compile; contentFiles; build; buildMultitargeting; buildTransitive; analyzers; native</PrivateAssets>
      </PackageReference>
  </ItemGroup>
