AsyncToSyncListBehaviorWrapper class
namespace: Serenity.Services assembly: Serenity.Net.Services
Wraps an IListBehaviorAsync implementation and exposes it as an IListBehaviorSync by blocking on its async methods. This allows synchronous list request handlers to run asynchronous list behaviors.

Remarks
A behavior instance is always cached and reused across requests, so make sure you don't store anything in private variables, and its operation is thread-safe. If you need to pass some state between events, use handler's StateBag.
This is a bridging adapter that blocks on the wrapped asynchronous behavior (sync-over-async). The synchronous interface exposes no CancellationToken, so a cancellation token from an asynchronous call site cannot be observed by the wrapped behavior. Prefer invoking the asynchronous behavior directly whenever a cancellation token is available.
