\"\"<\/a>An updated version of AsyncLock<\/code> has just been released on GitHub<\/a> and Nuget<\/a> with improved support for reentrancy detection.<\/p>\n

AsyncLock<\/code> is a async\/await-native anonymous lock for .NET and .NET Core that allows safely using async\/await while holding a lock, for example:<\/p>\n

<\/p>\n

 <\/div>\n
class AsyncLockTest\r\n{\r\n    AsyncLock _lock = new AsyncLock();\r\n\r\n    void Test()\r\n    {\r\n        \/\/ The code below will be run immediately and asynchronously.\r\n        \/\/ It *may* be run in a new thread, but we can't know.\r\n        Task.Run(async () => {\r\n            \/\/ This first LockAsync() call should not block\r\n            using (await _lock.LockAsync())\r\n            {\r\n                \/\/ This second call to LockAsync() will be recognized\r\n                \/\/ as being a ree\u0308ntrant call and go through\r\n                using (await _lock.LockAsync())\r\n                {\r\n                    \/\/ We now hold the lock exclusively and no one else\r\n                    \/\/ can use it for 1 minute\r\n                    await Task.Delay(TimeSpan.FromMinutes(1));\r\n                }\r\n            }\r\n        }).Wait(TimeSpan.FromSeconds(30));\r\n\r\n        \/\/ This call to obtain the lock is synchronously made from the main\r\n        \/\/ thread. It will, however, block until the asynchronous code which\r\n        \/\/ obtained the lock above finishes\r\n        using (_lock.Lock())\r\n        {\r\n            \/\/ We have now obtained exclusive access\r\n        }\r\n    }\r\n}\r\n<\/code><\/pre>\n
