A race condition in ASP.NET threading occurs when two or more threads access shared data simultaneously, leading to unpredictable outcomes. This can cause application instability and incorrect results.
To prevent race conditions, employ synchronization techniques such as locks, mutexes, or semaphores. For example, use the ‘lock’ keyword in C# to ensure only one thread accesses a critical section at a time:
private static object _syncLock = new object();
public void UpdateSharedData()
// Critical section code here
Additionally, consider using concurrent collections like ConcurrentDictionary or ConcurrentQueue, which are designed for multi-threaded scenarios. Alternatively, utilize Task Parallel Library (TPL) or async/await patterns to manage concurrency effectively without manual synchronization.
