Can you explain how asynchronous code execution works with the async method?

In C#, the keyword async is used to denote a method that executes asynchronously, meaning it does not block the calling thread while waiting for the operation to complete.

When a method is marked as async, it usually returns a Task or Task<T>. Inside such a method, you can use the await operator to asynchronously wait for the result of another operation without blocking the thread.

Example:

public async Task<string> GetDataAsync()
{
    // Asynchronously wait for the operation to complete, e.g., a network request
    string result = await SomeHttpClient.GetStringAsync("https://example.com");
    return result;
}

Here, await pauses the execution of the method until the result is obtained, but does not block the thread, allowing other tasks to run. After the operation completes, the method continues from where it left off at await. This improves application responsiveness and resource utilization.
