Displaying a Webpage in a WebView Within a Window Programmatically Using MonoMac

Question

I really didn't want to have to ask this here, because it seems to me this should be really basic and simple, but I can't find any good examples online after searching for several hours between yesterday and today. So, here goes:

I'm trying to experiment with an API that uses OAuth 2.0 authentication. In order to do that authentication, I'm trying to open a window with a webpage in it for the user to grant access to the application. For some reason, I thought this would be as simple as creating a new NSWindow and WebView, setting the content of the window to the WebView, and loading the page URL; however, when I run this, the window opens, but never displays anything. I tried using autolayout constraints, thinking maybe the webview just wasn't positioned properly, but that didn't work either. I took them out of the code below. I'm trying to do this in a xibless manner. Below is my code:

using AppKit;
using Foundation;
using CoreGraphics;
using WebKit;

namespace SampleApplication.Mac
{
    [Register ("AppDelegate")]
    public class AppDelegate : NSApplicationDelegate
    {
        public AppDelegate ()
        {
        }

        public override void DidFinishLaunching (NSNotification notification)
        {
            var window = new NSWindow (new CGRect (0, 0, 100, 100), NSWindowStyle.Borderless, NSBackingStore.Buffered, false);
            var webview = new WebView();
            webview.Frame = new CGRect (0, 0, 100, 100);
            window.ContentView = webview;
            webview.MainFrame.LoadRequest(new NSUrlRequest (new NSUrl ("https://google.com")));
        }

        public override void WillTerminate (NSNotification notification)
        {
            // Blah
        }
    }
}

I've done some Mac development before, but I've never used WebKit, so I might be missing some understanding somewhere. Any help would be greatly appreciated, as the documentation on this is not very good.

Well, it turns out the problem had nothing to do with the WebView at all. I feel really dumb about this, but the window that was showing up was the default one that is part of the Cocoa app template I used when I created the project. The window I was trying to make was not showing up at all! I kind of thought the dimensions seemed odd.

In order to fix this, I simply needed to do the following after instantiating the window:

window.MakeKeyAndOrderFront(null);

Once I did this, the window displayed and the webpage loaded as I expected.
