When querying against a property that is defined as an abstract base type the driver fails to handle a cast to a concrete type within the where clause.
The following example worked within the 1.92 of the C# driver.
Below is an example:
public class Entity { public A Result { get; set; } } [BsonKnownTypes(new Type[] { typeof(B), typeof(C)})] public abstract class A { public string Id { get; set; } } public class B : A { public string PropertyOnB { get; set; } } public class C : A { public string PropertyOnC { get; set; } }
Query:
collection.AsQueryable().Where(q => ((B)q.Result).PropertyOnB == "TestResult").ToList(); Executing this query gives the following exception: Convert({document}{Results}).PropertyOnB is not supported
