Hi, I'm using your code to interact with IB gateway. The problem occurs when I call a method twice or more. Why all times I get "A task was canceled" error? I'm doing something wrong?. Sorry I'm new with Task on .Net and Cancellation tokens.

Hi Korshak,

Can you try to place all that in an async Main() and call the api with "await twsController.Connect()" and "await twsController.GetAccountDetails()". If that doesnt work, please try to make a call to PlaceOrder (or any other API) and tell me if it works.

Please be sure to log into your paper account while testing. I see that you are on port 4002, which is default for live accounts. Be careful.

Hi @Korshack , I agree with @amittleider. When writing async code, you should avoid .Wait() and .Result if possible because you block the thread. Instead, await the async method and ensure you use async all the way down the call stack. You can make the main method async now as of C# 7.1.
