(INELEGANT?) SOLUTION:

I watched this excellent video https://www.youtube.com/watch?v=elfqejow5hM by Alexander Schmidt and at 33:00 the author reveals that the connection string should not be an EF connection string (using the EF provider) but should be a vanilla MYSQL/SQLServer connection string specifically set up for security, ie:

and similarly the identity model should be adjusted to:

Public Class ApplicationDbContext
    Inherits IdentityDbContext(Of ApplicationUser)
    Public Sub New()
        MyBase.New("IMSSecurityEntities")
    End Sub

This makes me nervous about accessing the security entities through the ORM - but I guess may well be by design so maybe no loss.
