Error while validating the service descriptor 'ServiceType

An error occurred while accessing the Microsoft.Extensions.Hosting services. Continuing without the application service provider. Error: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: DuoeCore.ServiceSqlite.Interface.ImAdminUserService Lifetime: Transient ImplementationType: DuoeCore.ServiceSqlite.Implement.mAdminUserService': Unable to resolve service for type 'DuoeCore.DataSqlite.DbContextSqlLite' while attempting to activate 'DuoeCore.ServiceSqlite.Implement.mAdminUserService'.)

出现以上错误问题，发现是我注入的DBContext上下文错误，两个重名的类，不在同一个类库里，本来调用B，结果自动调用了A造成如上错误。
