MailBee.NET Objects v11 adds support for .NET Core, Universal Windows, Exchange Web Services

Tuesday, 14 March 2017

The new major version of MailBee.NET Objects is here at last. It adds support of trending .NET Core and Universal Windows platforms as well as a new component, EWS, which lets your apps communicate with MS Exchange server via its native protocol.

MailBee.NET Objects now ships with a so-called .NET Standard compatible .DLL which supports .NET Core 1.0/1.1, Xamarin.Android, Xamarin.iOS. This includes ASP.NET Core as well.

We also added a UWP (UAP 10.0) compatible .DLL which lets you develop mail-enabled Universal Windows applications you can then run on any Windows platform.

To find out how to use MailBee.NET library for these platforms, refer to .NET Core Edition and and UWP Edition topics in the documentation.

EWS component (available for classic .NET Framework v3.5 and higher) is a wrapper for EWS Managed API which lets you send, receive and manage mail, contacts other kinds of Exchange items via web services. Not only that EWS is more flexible than IMAP/SMTP, EWS is often the only service enabled in Exchange and you may simply have no other choice but to use it instead of IMAP or SMTP. You can use it with both on-premises Exchange and Office 365.

Other cool features:

  • International e-mail addresses (IDN domains).
  • Mail parser can now embed inline attachments as base64 data in HTML body.
  • Improved TLS auto-selection (up to TLS 1.2) with the new TlsAuto option.
  • Secure direct send when MX server supports STARTTLS.
  • Outlook 2016 .MSG format.
  • Distribution lists in Outlook .PST files.
  • Imap.GetSpecialFolder method to locate special folder likes Sent Items.
  • And much more, check Version History for details.
