Hello,
I am building a background worker by following the docs and for some reason i can't inject any repository. When i try to inject the IUserRepository i get the exception on this message and when i try to inject a repository created with ABP Suite i get that the DbContext has already been disposed.
If you're creating a bug/problem report, please include followings:
ABP Framework version: v4.4.2
UI type: MVC
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): no
Exception message and stack trace:
Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'Volo.Abp.Users.IUserRepository`1[[Test.Users.AppUser, Test.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

The requested service 'Volo.Abp.Users.IUserRepository`1[[Test.Users.AppUser, Test.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' has not been registered
Can you resolve IUserRepository< AppUser> service in App Service?

Hello,
Sorry, IUserRepository<AppUser> does not work even on services but IRepository<AppUser, Guid> does work, but on background worker it says that the DBContext has already been disposed.

I guess you are using the Unify DbContext, So you should using
IRepository<IdentityUser, Guid>.https://community.abp.io/articles/unifying-dbcontexts-for-ef-core-removing-the-ef-core-migrations-project-nsyhrtna
but on background worker it says that the DBContext has already been disposed.
Please try to start a new uow in your background worker method.
