Connect and share knowledge within a single location that is structured and easy to search. in services. You can read more about this approach inASP.NET Core Dependency Injection Registering Implementations Using Delegates. In the second registration, AddSingleton also adds a constraint requiring that TService be a class (or interface) and that TImplementation is a class, which inherits from that interface. Adds the specified TService as a Transient service a binding between the TClient type and a named HttpClient. However, it does illustrate that we can take control when we need to.A second use case for this technique is when you wish to conditionally decide on an instance to return based on application configuration. using the factory specified in implementationFactory In our application, that will be until the process exits. Having a DI framework right there ready to be used means less time trying to set up a boilerplate project.
