Cannot implement interface because '<element>' cannot be found

Class Designer could not implement the interface because the code element that you entered either does not exist or is not defined in your project.

To correct this error

• Ensure that the code element that you entered is an existing interface.

• If the code element that you entered is defined outside your project, ensure that you have included the correct references in Solution Explorer.
