EmptyServiceProvider.cs

Provides an IServiceProvider that contains no application services.

public ref class EmptyServiceProvider sealed : IServiceProvider, Microsoft::Extensions::DependencyInjection::IKeyedServiceProvider, Microsoft::Extensions::DependencyInjection::IServiceProviderIsKeyedService

public sealed class EmptyServiceProvider : IServiceProvider, Microsoft.Extensions.DependencyInjection.IKeyedServiceProvider, Microsoft.Extensions.DependencyInjection.IServiceProviderIsKeyedService

type EmptyServiceProvider = class
    interface IKeyedServiceProvider
    interface IServiceProvider
    interface IServiceProviderIsKeyedService
    interface IServiceProviderIsService

Public NotInheritable Class EmptyServiceProvider
Implements IKeyedServiceProvider, IServiceProvider, IServiceProviderIsKeyedService

EmptyServiceProvider

Implements

IKeyedServiceProvider IServiceProviderIsKeyedService IServiceProviderIsService IServiceProvider

Remarks

Like the IServiceProvider returned by new ServiceCollection().BuildServiceProvider(), this provider still exposes the built-in services (IServiceProvider, IServiceScopeFactory, IServiceProviderIsService and IServiceProviderIsKeyedService) and resolves requests for IEnumerable<T> to an empty sequence.

Use Instance to access the shared singleton instead of writing a custom empty provider.

Properties

Name	Description
Instance	Gets the shared EmptyServiceProvider instance.
