entity framework core - Cannot override OnConfiguring in beta5 - no suitable method found to override -

after updating ef7 beta5 beta4 onconfiguring stopped working.

protected override void onconfiguring(dbcontextoptionsbuilder optionsbuilder) 

i can't figure out need write instead.

here's project.json, in case

{     "dependencies": {         "entityframework.sqlserver": "7.0.0-beta5",         "entityframework.commands": "7.0.0-beta5",         ...     } } 

it doesn't have "entityframework": "7.0.0-beta4" (no beta5 yet). apparently isn't needed.

you need use entityoptionsbuilder in beta 5 (and dbcontextoptionsbuilder in beta 6)
