[🐛 Bug]: [dotnet] Many WebSocketExceptions from BiDi if browser exits before disposal #16134
Description
Description
If the browser process exits before a BiDi is disposed (e.g. due to the user pressing close button, or due to an interrupt as in #16090 (comment)) , it causes many (infinite?) WebSocketExceptions to be logged.
Reproducible Code
using OpenQA.Selenium.BiDi; using OpenQA.Selenium.Firefox; using System; using System.Threading; using var webDriver = new FirefoxDriver(new FirefoxOptions() { UseWebSocketUrl = true, }); await using var bidi = await webDriver.AsBiDiAsync().ConfigureAwait(false); Thread.Sleep(TimeSpan.FromSeconds(100)); // Kill browser process to produce WebSocketExceptionsDebugging Logs
