How to Instantiate ODataQueryOptions

Sure. ODataPath is a list of ODataPathSegment(s) which should follow up the OData Uri spec.

In Web API OData, it's easy to instantiate an ODataPath, for example:

IEdmModel model = GetEdmModel(); 
IEdmEntitySet entitySet = model.EntityContainer.FindEntitySet(setName); 
ODataPath path = new ODataPath(new EntitySetPathSegment(entitySet)); 

The above path follows up the OData spec that it has the odata template as:

~/entityset
