Hi Guys. I'm trying to implement OData on my ASP.Net Core 5 API. I can retrieve books using the Get. But I am struggling to do a POST. When I try to use the POST on Postman, the CreateBookDto properties all return null. I tried to add [FromBody] that does not work also. The only time this seems to work is when I decorate the controller with [ApiController] but that in turn affects my GET. I'm not sure what to do anymore.
