For those finding this question in dotnet core. I found a solution here
Code:
private void OpenUrl(string url)
{
try
{
Process.Start(url);
}
catch
{
// 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;
}
}
}
