Some final comments mostly related to tests/simplifying the conversion logic as that was quite hard to grasp/follow. In addition to that, some extra tests you might want to add:
- Tests for object matches that use embedded objects. You can use
ObjectWithEmbeddedPropertiesandEmbeddedAllTypesObject. Then, the tests should verify that this works:realm.All<ObjectWithEmbeddedProperties>().Filter("AllTypesObject = $0", theEmbedded) - Test that
nullis passed correctly as a value. e.g.realm.All<Foo>().Filter("Prop = null")should be equivalent byrealm.All<Foo>().Filter("Prop = $0", (int?)null)(assumingPropisint?). Note that you need the explicit cast as implicit null casts don't work yet and may not work due to reasons @papafe will explain on Wednesday.
…edded obj to have Guid, ObjectId and byte[]

Description
Adding support for value substitution meant updating the wrapper to supply an array of mixed value to core. And from the C# side passing a marshable array of PrimitiveValue to the wrappers.
Documentation for the syntax of value substitution can be found here.
Fixes #1822
TODO
Nothing left
=============================
UPDATE:
RealmValueType.Nullto core when an in-memory object is supplied. This will need to be corrected, but not by this PR.
