Hi all,

I am developing an addin that runs an instance of FileSystemWatcher to watch a folder if any file is been creating in it. So, when a file created, i read the email of a contact from file and trying to open the contact as recordcontext. But i am getting an error as attached. There is no WinForm control in my project, so InvokeRequired-Invoke solution doesn't work out.

Could anyone please tell me how i can solve this problem?
