Interface ISessionServiceLock<TService>

Namespace

MVVrus.AspNetCore.ActiveSession

Assembly

MVVrus.AspNetCore.ActiveSession.dll

This generic interface is intended to obtain an exclusive access to a scoped service instance within the current active session's service scope (if any).

public interface ISessionServiceLock<TService>

Type Parameters

TService

Type of the service to which the exclusive access to be obtained

Remarks

This interface is registered as a scoped service in the application's DI container as a part of registering the ActivesSession infrastracture services. It is designed to be obtained from a request's scope.

If no active session for a request is available, the process of obtaining an exclusive accessor for a service performed by this ISessionServiceLock service falls back to the request's scope DI container. This is done for compatibility reason: a service accessor obtained this way may be used by a request handler irrespective of existence of an active session for the request. Because scoped service instances from request DI containers are never shared between requests, the service accessor ILockedSessionService<TService> obtained from the request's scope DI container doesn't really represent any lock, so many of such accessors for different requests may be obtained simultaneously.

Methods

AcquireAsync(TimeSpan, CancellationToken)

Obtains an exclusive service accessor asynchronously.
