Unhandled Exception thrown at arbitrary time

[Lumaswell]

If you run the websocket long enough, it'll eventually throw an unhandled exception in 'System.Net.WebSockets.WebSocketException' in System.Net.WebSockets.dll. I'm an amateur coder at best, so I don't know how to debug this. I'm pasting the debug windows and the call stack below. Code built in visual studio 2022, .net standard 8.0, windows forms app, c#

Debug output: Exception thrown: 'System.Net.WebSockets.WebSocketException' in System.Net.WebSockets.dll Exception thrown: 'System.Net.WebSockets.WebSocketException' in System.Private.CoreLib.dll Exception thrown: 'System.Net.WebSockets.WebSocketException' in System.Net.WebSockets.dll Exception thrown: 'System.Net.WebSockets.WebSocketException' in System.Private.CoreLib.dll Exception thrown: 'System.Net.WebSockets.WebSocketException' in System.Private.CoreLib.dll 'BackToCoinbase2023.exe' (CoreCLR: clrhost): Loaded 'C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.1\System.Diagnostics.StackTrace.dll'.

Update: So after much work, the websocket is getting put into a state of "Aborted". I'm currently attempting to figure out how to reset this as closing the websocket does not function in this state.

@Lumaswell Good day, I know your issues was from Feb so I apologize for not getting back to you as I've been quite busy. I have just updated the project with many modifications. Specific to your issue, I have implemented the following:

1. I have increased the buffer size of the WebSocket to 5MB as it was originally very low (128KB)
2. I have also added an optional WebSocket buffer size to the CoinbaseClient constructor if you'd like set a custom buffer size for your needs
3. Added a property within the WebSocketManager called WebSocketState that will return the state of the websocket. You can use this to trigger off a reconnection if required.
4. I have added another WebSocket Test application called WebSocketReconnectionTestApp to the solution which demonstrates the use of this new property as well as a Subscriptions property to show which channels are currently subscribed to. In addition, the test application triggers a disconnect and reconnect every 30 seconds to demo how to reconnect based on the WebSocketState.

Hope this helps resolve this issue. Thanks! Barry
