How to programmatically set registry setting to prevent Outlook from removing the VSTO Addin

Question

Hi is there a way to programatically set the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Resiliency\DoNotDisableAddinList\

with DWORD= 1

As I learned from this posting (among many others) this prevents Outlook from removing my Addin from Outlook for being slow. Yes, it would be better to design the AddIn for being faster. But as it needs to connect service on the internet this will be hard to achieve. BTW: I have this problem also with many other Addins.

You need to use .Net base class libraries to get the job done, the RegistryKey class represents a key-level node in the Windows registry. See How to: Create a Key In the Registry (Visual C#) for more information.
