When making an application I ran into the issue where every time I revisited the page with a ShowOpenDialogAsync function tied to a button it would open an additional instance of the dialog.

Using .Net 5, ElectronNET.API v13.5.1 & Node.JS v16.18.1.
I've reduced the issue to the basics and made a separate repository.

Are you sure you're not binding the click event multiple times? What happens when you replace

document.getElementById("select-directory").addEventListener("click", () => {
  ipcRenderer.send("select-directory");
});

with

document.getElementById("select-directory").addEventListener("click", () => {
  alert('clicked');
});

?

It just sends the alert once but still opens one additional window every time the page is re-visited.
