Error on reloading a window after a second window is closed

[dlitty]

• Version: latest (13.5.1)

• .NET 5

• Target: None; electronize start will reproduce

Using the latest Electron.NET API & CLI: if an application has two windows open, then one of them is closed, and you call Reload() on the first one, an error occurs:

A Javascript error occurred in the main process
Uncaught Exception: TypeError: Object has been destroyed
at BrowserWindow.<anonymous>( ... path ... /obj/Host/api/browserWindows.js:205:55 ...

Steps to Reproduce:

1. Create a new .NET 5 ASP.NET web application
2. Follow the instructions in the readme to set up Electron.NET in the project
3. Instead of Task.Run(async () => await Electron.WindowManager.CreateWindowAsync());, use:

    Task.Run(async () => 
    {
        var mainWindow = await Electron.WindowManager.CreateWindowAsync();
        var secondWindow = await Electron.WindowManager.CreateWindowAsync();
        secondWindow.Close();
        mainWindow.Reload();
    }

Alternatively, comment out the Close and Reload lines, and manually close one window and hit Cmd-R on the other.

Omg reproduction of a bug I couldn't figure out how to reproduce. And so simple! Thank you, you are my hero!

I'm going to fix this on Monday now that I have repo steps.

This bug has been on my annoyatron radar for months but never had the time to dive in depth to isolate and reproduce. Just happened randomly it seemed like.

Glad I could help! Never good to have the annoyatron active!

Uncaught Exception:
TypeError: Object has been destroyed
    at BrowserWindow.<anonymous> (D:\AllProjects\WebApplication2\Browser\bin\Desktop\win-unpacked\resources\app.asar\api\browserWindows.js:190:55)
    at BrowserWindow.emit (node:events:526:28)

I opened window A when the application started with a custom url scheme, and then used the custom url scheme to open the program, triggering the second instance event. I called CreateWindowAsync to create a new window B, then closed window B. When I clicked on the link on in window A,the link has js listening on code, I reported this error.

After window B is closed, if I open a new window, this situation will disappear

Outdated - use ElectronNET.Core and ElectronNET.Core.AspNet.
