C# New Lock Object C# 13

New Lock object

.NET 9 introduces a new thread synchronization type called System.Threading.Lock, which provides enhanced thread synchronization capabilities. Note that the runtime will detect whether the target of a lock is a Lock object, in which case it will use the updated API in lieu of the traditional API that uses System.Threading.Monitor. The compiler also will recognize if you convert a Lock object to some other type where System.Threading.Monitor code would be generated.

Let’s compare the old and new APIs. The code snippet below implements synchronization using the traditional API.

public class DbManager
{
    private object objLock = new object();
    public void InsertData()
    {
        lock (objLock)
        {
            //Your usual code to insert data to the database
        }
    }
}

To use the new API, you need to change only one line of code:

private System.Threading.Lock objLock = new System.Threading.Lock();

Hence, the updated DbManager class would have the following code.

public class DbManager
{
    private System.Threading.Lock objLock = new System.Threading.Lock();
    public void InsertData()
    {
        lock (objLock)
        {
            //Your usual code to insert data to the database
        }
    }


}
