Question

What are service lifetimes in .NET Core?

Answer 1

NET Core supports a design pattern called ‘Dependency Injection’ which helps in the implementation of IoC(Inversion of Control). During registration, dependencies require their lifetime to be defined. The lifetime of service decides under what condition the instance of the service will be created and till what time it will be live. 

 

There are three types of service lifetimes supported by .NET Core:

• Transient Service: Instance is created each time it is requested.
• Scoped Service: User-specific instance is created once per user and shared across all the requests.
• Singleton Service: Single Instance is created once a lifetime of the application.
