When I'm trying to add a new migration using the command line dotnet ef migrations add TicketStatuses I get the following error:
Unable to create an object of type 'IndoDbContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728
I have all well defined on the frameworkcore
namespace Indo.TicketStatus { public class EfCoreTicketStatusRepository : EfCoreRepository<IndoDbContext, TicketStatuses, Guid>, ITicketStatusRepository { public EfCoreTicketStatusRepository( IDbContextProvider<IndoDbContext> dbContextProvider) : base(dbContextProvider) { } } }
What's missing ?

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
- TicketStatuses
- Project.Domain.Shared
- TicketStatuses
- TicketStatusConsts.cs
- TicketStatuses
- Project.EntityFrameworkCore
- EfCoreTicketStatusRepository.cs
- Project.Application
- TicketStatuses
- TicketStatusesAppService.cs
- TicketStatuses
- Project.Application.Contracts
- TicketStatuses
- CreateTicketStatusDto.cs
- ITicketStatusAppService.cs
- TicketStatusDto.cs
- UpdateTicketStatusDto.cs
- TicketStatuses
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
- Project.Domain

hi
There is should be a
IndoDbContextFactory.csfile andMicrosoft.EntityFrameworkCore.Toolspackage in hteEntityFrameworkCoreproject./* 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> -
