I'm attempting to use Odata and web-api with mongoDb. The web-api library applies linq queries across an IQueryable in order to query it. One of the queries I'm required to support involves a cast. web-api returns an IQueryable with the expression

value.where(it => ((it.property as Child).Value == "example"));

This results in

Unable to determine the serialization information for the expression:
<TypeAs>it.Property.Value

is there a way to modify the expression once I get the IQueryable so that it performs an is check and then a cast, as this is supported by the C# driver. Alternatively is there a library which provides this support already?
