Hello, I am trying to use VB to send out email with more customized details & added the following code into XAML file to add the namespace named Microsoft.Office.Interop.Outlook:

<AssemblyReference>Microsoft.Office.Interop.Outlook</AssemblyReference>

No error is shown in Studio, but when i click Run, the Runtime error popped up:

Could anyone let me know how should I do to make the code running? THANK YOU！
