Using OnReadyToShow to display the main window in Blazor does not seem to work with Show set to false

ElectronNET version: 7.30.2 .NET Core 3.0.1 (produces the same issue with v3.1.0)

(project that reproduces the behavior is attached)

BlazorOnReadyToShowIssue.zip

Create an ElectronNET based Blazor project with the standard steps

1. mkdir BlazorOnReadyIssue
2. cd BlazorOnReadyIssue
3. dotnet new blazorserver --no-https
4. dotnet add package ElectronNET.API
5. dotnet new tool-manifest
6. dotnet tool install ElectronNET.CLI
7. dotnet electronize init
8. Set up Program.cs:

// ...
public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
             webBuilder
                 .UseStartup<Startup>()
                 .UseElectron(args);  // --- Added this
        });
// ...

1. Set up Startup.cs:

// --- At the end of Configure
// ...
Task.Run(async () =>
{
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(
        new BrowserWindowOptions
        {
            Title = "OnReadyToShow",
            Width = 1152,
            Height = 864,
            Show = false // --- When set to true, project works properly
        });
    browserWindow.OnReadyToShow += () => browserWindow.Show();
});

1. Run the project (either with Ctrl+F5 or electronize start)

Expected behavior: The Electron Shell window is displayed with the Blazor App.

Issue: The Electron Shell window does not display.

Whenever I change the Show property of BrowserWindopOptions to true, the project works fine, but, of course, for a few seconds an empty page is displayed according to the normal behavior.

Fixed in the next Electron.NET Version 8.31.1.

@Dotneteer We authors are both fathers at the moment… and are therefore a bit limited in time… I will work on a new version for the days… But you can also support or sponsor us with pull requests 😃

I’ll take a closer look at your problem.
