I have received a project from another developer and have built his project on my machine.

On startup - i am getting the following error:

Method not found: 'Boolean Examine.BuildingEmptyIndexOnStartupEventArgs.getIsHealthy()'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

The only thing that I can think of is that he upgraded from 7.5.10 to 7.6.1, but may have missed checking in a change that may affect Examine? (or i could be out to lunch).

Can anyone point me in the right direction or help in isolating where I could look to debug this?

thanks.
