Hangfire 1.8.0-beta1

An easy and reliable way to perform fire-and-forget, delayed and recurring, long-running, short-running, CPU or I/O intensive tasks inside ASP.NET applications. No Windows Service / Task Scheduler required. Even ASP.NET is not required. Backed by Redis, SQL Server, SQL Azure or MSMQ. This is a .NET alternative to Sidekiq, Resque and Celery. https://www.hangfire.io/

No packages depend on Hangfire.

Hangfire.SqlServer • Added – Recommended Schema 8 migration with fixed `JobQueue.Id` column to use `bigint` type. • Added – `SqlServerStorageOptions.PreferMicrosoftDataSqlClient` option to use the corresponding package. • Added – `SqlServerStorage.SchemaVersion` metric for Dashboard UI. • Added – Implement optional experimental transactional acknowledge for SQL Server (`UseTransactionalAcknowledge` option). • Changed – Sliding invisibility timeout-based fetching method is now used by default with 5 minute timeout. • Fixed – Ensure connection is released when exception is thrown when during lock release.
