You can integrate your legacy COM servers and ActiveX controls into managed applications by adding references to unmanaged DLLs to your project, and then browse the types just as you would with managed assemblies.

1. From the main menu, choose ProjectAdd Reference. The Add Reference dialog box appears.
2. Select either a legacy COM type library or ActiveX control to integrate into your managed application.
3. Click Add Reference. The reference is added to the text box.
4. Click OK.
   Tip: You can also right-click the References
   folder in the Project Manager, and choose Add Reference.
