I am now working on querying some fields that are mapped via Entity Framework to the Sql Server geography type. The following two queries:

queryable.Where("p.any(c.geographic.Union(@0).Area == 0)", parameters.ToArray());
queryable.Where("p.any(@0.Difference(c.geographic).IsEmpty)", parameters.ToArray());

result in the following error:

System.Linq.Dynamic.Core.Exceptions.ParseException: 'Methods on type 'DbGeography' are not accessible'

A simple geographic query, like the following, works as expected:

p.any(c.geographic.Intersects(@0))

The parameters object contains a single DbGeography object.

Are the above two queries expected to work? Do I maybe again have the incorrect query syntax?

Thanks!
