Lock keyword gets an upgrade in .NET9

In .NET 9, the lock keyword has been enhanced, addressing some long-standing limitations with .NET’s locking mechanisms. This upgrade aims to improve thread safety and performance, particularly for applications with complex concurrency needs. The new lock capabilities allow for more efficient and flexible locking options, helping developers manage resources in multi-threaded environments more effectively. This enhancement is part of Microsoft's ongoing efforts to optimize .NET for high-performance applications, making it a notable update for developers focused on building reliable and efficient software systems. https://mareks-082.medium.com/new-lock-object-and-history-d69877f46521
