static member AddHostedService : Microsoft.Extensions.DependencyInjection.IServiceCollection -> Microsoft.Extensions.DependencyInjection.IServiceCollection (requires 'HostedService : null and 'HostedService :> Microsoft.Extensions.Hosting.IHostedService)

<Extension()>
Public Function AddHostedService(Of THostedService As {Class, IHostedService}) (services As IServiceCollection) As IServiceCollection

Parâmetros de tipo

THostedService

Observação

Você não deve chamar esse método várias vezes para a mesma classe. Isso só registrará o primeiro HostedService que você fornecer. Para adicionar vários HostedServices, use AddSingleton<TService>(IServiceCollection) para cada implementação de IHostedService explicitamente.
