Using the ASP.NET WebApi 2 implementation of OData 3, I'm trying to apply the $select query option to the new IQueryable being returned from the new 2.1 RC driver. I keep running into this error when enumerating the IQueryable, however:

System.ArgumentException: Value type of serializer is System.Web.Http.OData.Query.Expressions.PropertyContainer+NamedProperty`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] and does not match member type System.Web.Http.OData.Query.Expressions.PropertyContainer.

The IQueryable debug view shows this:

DebugView ".Call System.Linq.Queryable.Select(
.Constant<MongoDB.Driver.Linq.IMongoQueryable`1[MyObject]>(aggregate([])),
'(.Lambda #Lambda1<System.Func`2[MyObject,System.Web.Http.OData.Query.Expressions.SelectExpandBinder+SelectSome`1[MyObject]]>))

.Lambda #Lambda1<System.Func`2[MyObject,System.Web.Http.OData.Query.Expressions.SelectExpandBinder+SelectSome`1[MyObject]]>(MyObject $var1)
{
.New System.Web.Http.OData.Query.Expressions.SelectExpandBinder+SelectSome`1[MyObject](){
ModelID = \"b5ae8d92-3fb0-4049-a9f2-c72805d87209\",
Container = .New System.Web.Http.OData.Query.Expressions.PropertyContainer+AutoSelectedNamedPropertyWithNext`1[System.String]()
{
Name = \"id\",
Value = $var1.id,
Next = .New System.Web.Http.OData.Query.Expressions.PropertyContainer+NamedProperty`1[System.String]()

{ Name = \"Name\", Value = $var1.Name }

}
}
}" string

So it seems like the value of Container (in System.Web.Http.OData.Query.Expressions.SelectExpandBinder+SelectSome) is actually not PropertyContainer (which is what's defined in the class), but a SubClass of it, hence causing the exception to be thrown.

Might there be a way to resolve this issue in SetSerializer?
