I got it working pretty much out of the box. There is just two things:

See #823 - you'll need to "tell" Blazor it's still in a browser. As the heuristic is pretty bad, it thinks its running in Node.js.
The HMR does not work with a weird message that jQuery is not loaded - my best guess is that VS does not inject the required code.

I think we can improve (1) to the point that there is a property "AllowBlazor" or "IsBlazorProcess" (or similar). When this property is set we introduce a preload script that will set process to undefined, leading to Blazor as it should.

For (2) I am still looking why exactly we run into this and what we can do to improve it. Will be also coming in.

Yeah I can make (2) also work like (1) - reason was that jQuery (which is part of browserLink) has a check to detect if its running in a CJS system. As module is also defined by Electron this was not working. Essentially same fix -> global.process = undefined; global.module = undefined.

Rolled out 0.2.0-pre.200:

builder.UseElectron(args, async () =>
{
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(
        new BrowserWindowOptions { Show = false, AutoHideMenuBar = true, IsRunningBlazor = false });

    browserWindow.OnReadyToShow += () => browserWindow.Show();
});

Release ETA is Monday.
