Introduction The article demonstrates the use of ConfigureAwait(false) efficiently to add deadlock-free asynchronous code. Learning Objectives How to use ConfigureAwait(false) instead of traditional async await programming Why ConfigureAwait(false) is better Prerequisites for Developers Basic understanding of C# programming language Basic understanding of asynchronous programming using async await Getting Started Consider an example where the user wants to load data asynchronously within a method. /// <summary>
    /// Old approach with classic async await 
    /// </summary>
    /// <returns></returns>
    public async static Task OldApproach()
    {
        await ReadDataAsync();
    } In this approach, the await operator waits for ReadDataAsync and then proceeds with execution in the same synchronization context from where it began. The aforementioned approach is used when the developer ensures that UI updates are executed in a separate thread. However, it may introduce potential deadlock risks. Optimized approach with ConfigureAwait(false) Let’s transform the above method using ConfigureAwait(false) /// <summary>
    /// Optimized approach with ConfigureAwait
    /// </summary>
    /// <returns></returns>
    public static async Task OptimizedApproachAsync()
    {
        await ReadDataAsync().ConfigureAwait(false);
    } By adding this, the compiler doesn't add the execution in the same synchronization context, which reduces the chances of deadlocks. The aforementioned optimization is beneficial in non-UI applications like library code, etc. Why ConfigureAwait(false) is better Please find below the benefits of using ConfigureAwait(false) method Improved Performance As the optimized approach doesn’t add the execution to the same synchronization context, it saves on extra overhead and helps create scalable applications. Reduce chances of deadlocks ConfigureAwait(false) method mitigates the risk of deadlocks when the synchronization context is blocked. Conclusion The ConfigureAwait(false) method in C# aims to craft efficient, deadlock-avoidant asynchronous code. Its advantages are particularly beneficial in non-UI applications and in library projects.
