Can you provide a failing unit test with the bare minimum to reproduce the
error?

in 5.1.0 working.

new problem

.Where(x => x.InternalId != "")

=>

internal_id <> ''''' or internal_id is null

why is that?

This is intended because of the difference of null semantic in SQL and .NET

In SQL null does not equal nor does not not-equal to anything (any
comparison expression involving null gives false). So the expression null
<> "" is false.

In .NET null behaves as a normal object.

Alexander
