entity framework - Oracle Developer Tools for VS2013 throwing object reference error -

-

i have following installed:

vs 2013 oracle 11g database oracle developer tools vs 2013 12.1.2400 odp.net 12.1.2400 ef 6

after add or select new connection when adding new ado.net entity data model, "object reference not set instance of object" error , not able add new model.

error screen shot

this working when had devart oracle client installed (although wasn't using it). after uninstalled devart components started error.

i have since uninstalled , re-installed oracle developer tools , odp.net still same error.

i able connect oracle database via server explorer within vs.

any ideas? it's driving me mad.

i decided give on vs 2013 , installed vs 2015 planning on doing anyway.

in vs 2015 got same "object reference error" when trying add new project. found thread: error message "no exports found match constraint contract name" had solution that.

i installed oracle developer tools vs 2015 (the msi version) , it's working. still not working in vs 2013, abandon it.

i suspect uninstalling devart component caused issue.
