Issues with Async/Await and Task Continuation in C# 10 Web API
Hey everyone, I'm running into an issue that's driving me crazy. I'm dealing with I'm facing an issue with asynchronous method execution in my C# 10 Web API... I have an endpoint that processes a request and waits for a database call to complete, but I'm getting a `System.InvalidOperationException: The operation cannot be completed because the operation is in progress` error intermittently. Here’s the relevant part of my code: ```csharp [HttpGet] public async Task<IActionResult> GetDataAsync(int id) { var result = await ProcessDataAsync(id); return Ok(result); } private async Task<MyData> ProcessDataAsync(int id) { var data = await _context.MyData.FindAsync(id); // Simulate some processing await Task.Delay(1000); return data; } ``` I've ensured that `_context` is properly instantiated and that I'm not calling `await` on the same task multiple times. However, I noticed that any concurrent requests to this endpoint may lead to the `InvalidOperationException` due to overlapping executions. I've tried wrapping the `await` calls with a lock: ```csharp private static readonly object _lock = new object(); private async Task<MyData> ProcessDataAsync(int id) { lock (_lock) { var data = await _context.MyData.FindAsync(id); // Simulate some processing await Task.Delay(1000); return data; } } ``` This caused a deadlock instead of resolving the issue. I suspect I'm mismanaging the async flow or the context state. Is there a recommended way to handle this scenario in a web API that processes concurrent requests without running into these exceptions? I've been using C# for about a year now. Could this be a known issue?
