Question regarding complex path to entities

[EternaleapFromPit]

Hi

It's not obvious whether it's possible to provide complex path like that somehow:
builder.HasIndex(entity => new { entity.UpperLevelField, entity.InternalMappedInstance.Field }).IsUnique()
Wheh I use it like that it gives the error. Providing char array doesn't work too.

Regards,
Vlad.

As you found out, that syntax is not supported.
