Please help. I'm getting the following error on PostInitialize of my WebMVC module application. Please advise - I have reviewed module dependencies and I am not sure what the DI system is looking for here / what convention I have broken:
Castle.MicroKernel.Handlers.HandlerException HResult=0x80131500 Message=Can't create component 'Abp.MultiTenancy.AbpTenantManager'2[[MyCompany.MySystem.MultiTenancy.Tenant, MyCompany.MySystem.Core, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null],[MyCompany.MySystem.Authorization.Users.User, MyCompany.MySystem.Core, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]]_9d905d3e-a891-4b74-a909-026b8044ccf5' **as it has dependencies to be satisfied.

Generally, this will not happen if you have not modified the default project dependencies.
Does your
MySystemEntityFrameworkCoreModuledepend onAbpZeroCoreEntityFrameworkCoreModule? Does theAbpZeroDbMigratorclass exist in the MySystemEntityFrameworkCore project?public class AbpZeroDbMigrator : AbpZeroDbMigrator<AbpZeroTemplateDbContext> { public AbpZeroDbMigrator( IUnitOfWorkManager unitOfWorkManager, IDbPerTenantConnectionStringResolver connectionStringResolver, IDbContextResolver dbContextResolver) : base( unitOfWorkManager, connectionStringResolver, dbContextResolver) { } } -

Thanks for the feedback - it helped me to resolve the problem.
I renamed my
AbpZeroDbMigratorclass toMySystemDbMigrator. After changing it back, the service now successfully resolves.It seems there is a hard-coded dependency on this class name to resolve the
IAbpZeroDbMigratorservice, correct? I would like to suggest that for issue resolution it would be most helpful if all DI and naming conventions / hard-coded project dependencies were documented in a single place. -

public override void Initialize() { IocManager.RegisterAssemblyByConvention(typeof(AbpZeroCoreEntityFrameworkCoreModule).GetAssembly()); }Automatic registration by default according to the name convention, If you change the name you need to register it manually.
