问题
Couldn't find group by references in ODATA V4 documentation. When we pass group by query in URL it just returns the key, not the actual grouped results.
Any references for using Group by in Asp.Net ODATA, on extensibility points of ODATA Web API. We're in need to take full command over how ODATA query is parsed & transformed into LILNQ to entities query.
I am talking on the line of intercepting ODATA queries and performing manual customisation e.g. LINQ to Entities
I am trying to achieve similar extension for Case Sensitivity. OData Case In-Sensitive filtering in Web API?
