Hello, thank you for your answer, Here is the $odata report In this example it is class1 that does not work  

I renamed id by key and it works, I left attribute [Route("api/[Controller]")] 

Indeed you are right, by putting [Route("api/class1")] I have endpoints for odata and separate api, so I can use odata or standard api. here's the report   Thanks...
