Does adapter.SaveEntityCollection work only on fetched entities or can it be applied to newly created entity collection ?

                Dim sharedRoleQueries As New EntityCollection(New SharedRoleQueryEntityFactory)
                For idx As Integer = 0 To shareWithRoleIds.Count - 1
                    sharedRoleQueries.Add(SharedRoleQueryManager.Create(fromUserId, queryId, CType(shareWithRoleIds(idx), Integer), Now))
                Next

               SharedRoleQueryManager.SaveCollection(sharedRoleQuery)

SaveCollection just calls adapter's SaveEntityCollection method, but nothing happens. Since help talks only about working with collections after fetching it I wonder if need to loop through each entity in collection and save it?

SaveEntityCollection definitely works on new objects.

Add the following to your app.config to see the SQL being generated.

<system.diagnostics>
    <switches>
        <add name="SqlServerDQE" value="3" />
    </switches>
</system.diagnostics>

Search for SqlServerDQE to see switches for other databases.

Thanks for a response, problem was somewhere else, there was nothing in collection to begin with.
