I try to create an new email item with MS Outlook (2016, x64 & on Win11):

Dim appOutlook = CreateObject("Outlook.Application")
Dim appOutlookMsg = appOutlook.CreateItem(0)

The 2nd line fails with error message:
System.MissingMemberException: "Public member 'CreateItem' on type 'Application' not found."

The application itself is complied as x64 and also "CreateObject" opens a MS Outlook instance.
On my business machine both code lines are working (Office 365 BUT x86, Win10)!

Any ideas why it does not work?

What I have tried:

I checked if the member could be exposed (failed as well):
It seems that only the members from the application object are accessible and not members from the implemented interface "_application".
I also tried to create an new Excel workwook with LateBinding; failed too.

I installed also MS Office 2019 (x86) after deinstallation of previous version and got same error message.

Ok, I installed VS2019 as well (used previously VS2022 with .net5.0) and now with Framework 4.5 it works ...
I tested also Framework 4.8 and it worked too. So it seems that the issue is with VS2022 & >= .Net5.0

It works with c# and .net5 as well; it is only an iusse with vb code.
