Send email using the installed mail client in .Net

How can I send an email without attachments using the default email client installed on Windows 10/8/7.

I tried the following code but it is just opening a blank page in the Chrome browser.

    var url = "mailto:someone@somewhere.com?subject=Test&body=Hello";    System.Diagnostics.Process.Start(url);

I can fix it by changing the Default mail client from Google Chrome to MS Outlook, but shouldn't the Google Chrome smartly open Gmail?
