Launch browser from Xamarin.Mac app

martin_scholz

I try to open a browser in my Xamarin.Mac application like this

var url = getLaunchUrl(sessionId);
                try
                {
                    Process.Start(url);
                }
                catch ( Exception ex)
                {
                    // hack because of this: https://github.com/dotnet/corefx/issues/10361
                    if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
                    {
                        url = url.Replace("&", "^&");
                        Process.Start(new ProcessStartInfo("cmd", $"/c start {url}") { CreateNoWindow = true });
                    }
                    else if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
                    {
                        Process.Start("xdg-open", url);
                    }
                    else if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
                    {
                        Process.Start("open", url);
                    }
                    else
                    {
                        throw;
                    }
                }

but nothing happens. Anything I'm doing wrong?

I think i got it. I need to url encode it before pass it to Process.Start.

I test simply with Process.Start("https://www.google.com"); on mac (Catalina), it works fine .

Which platform did you test on ? Which is the OS version ?
