    You can create mime (*.eml) files using MimeKit (https://github.com/jstedfast/MimeKit). These can be opened in Outlook the same as msg. If you need to send them you can use another library from the same author - MailKit.

    Can confirm. When I wrote some benchmark tests for [MimeKit](https://github.com/jstedfast/MimeKit), I noticed something close to a 10% (IIRC) performance increase compared to .NET Framework (4.x). Needless to say, I was impressed.
  • Good C# Source Code

    I would argue that my MimeKit and MailKit projects are some examples of good code, but I'm probably biased ;-)

    Take a look at the MessageReader sample code. It shows how to display a message using a BrowserControl which is probably very similar to a WebView. Unfortunately, the sample is in C# and not VB, so it will need some adjustments.
