Vous pouvez make an interface to your application-level Add-In available to other Add-Ins.
You can expose an object in an VSTO Add-in to the following types of solutions:
- Visual Basic for Applications (VBA) code in a document that is loaded in the same application process as your VSTO Add-in.
- Document-level customizations that are loaded in the same application process as your VSTO Add-in.
- Other VSTO Add-ins created by using the Office project templates in Visual Studio.
- COM VSTO Add-ins (that is, VSTO Add-ins that implement the IDTExtensibility2 interface directly).
- Any solution that is running in a different process than your VSTO Add-in (these types of solutions are also named out-of-process clients). These include applications that automate an Office application, such as a Windows Forms or console application, and VSTO Add-ins that are loaded in a different process.
