One particular error, WaitingForActivation “Not yet computed”, can signal that your async method isn't functioning as expected. In this guide, we will break down the problem, explore what causes it, and show you the solution step-by-step. The Problem: Async Method Not Yielding Results Consider the following scenario: You have an async method that is supposed to call another async function twice. However, on the second call, you receive a message indicating that the result is "Not yet computed." This can lead to confusion and frustration, especially when you expect the code to work as intended. Example Code Causing the Error [[See Video to Reveal this Text or Code Snippet]] Analyzing the Code and Debugging the Issue Upon reviewing the code snippet, the main issues arise from two points: Multiple Awaits on the Same Task: You are awaiting the dwnldKeybankListTask twice and ignoring the dwnldAOCListTask. Inappropriate Usage of async void: The method is defined as async void, which complicates error handling and execution flow in async methods. The Solution: Correcting the Code Here's how you can resolve the WaitingForActivation error and optimize your async method for better readability and performance: Step-by-Step Correction Use async Task Instead of async void: This allows for better task management and error handling. Await Each Task Properly: Ensure that you await both tasks appropriately. Updated Code Here’s the corrected version of your async method: [[See Video to Reveal this Text or Code Snippet]] Best Practices for Async Programming in C# Always Prefer async Task Over async void: This is especially important for public methods where you need to handle exceptions or manage task completions seamlessly. Avoid Using the Same Task Multiple Times: Always create new tasks for different operations to avoid conflicts and errors. Be Careful with Variable Naming: Clear and descriptive names can help in maintaining code and understanding logic quickly. Conclusion Asynchronous programming in C# can be tricky, and encountering errors like WaitingForActivation can lead to confusion. By following best practices and ensuring that you properly await tasks, you can avoid these pitfalls and enhance your code's performance and readability.
