Question

I’ve got a table FeeMetadata with a PK FeeID BIGINT IDENTITY(1,1) NOT NULL

This table contains two 1-1 relationships. One to PFD.Fees, and one to SoaCourt.Fees via the FeeID column (same name in all three tables, only the metadata table is marked as IDENTITY, the other two tables this column is PK but NOT identity)

Here’s the code for the EF classes:

Namespace PFD

    <Table("FeeMetadata", Schema:="PFD")>
    Public Class FeeMetadata
        Public Sub New()
            MyBase.New()
        End Sub

        Public Sub New(ByVal tFee As SOACourt_v1)
            Me.New()

            Me.GroupKey = tFee.DriverLicenseNumber
            Me.PfdFee = New PFD.Fee(tFee)
            Me.SoaCourtFee = New SoaCourt.Fee(tFee)
        End Sub

        <Key>
        <DatabaseGenerated(DatabaseGeneratedOption.Identity)>
        Public Property FeeID As Int64

        ' Other domain-specific properties...

        Public Property SoaCourtFee As SoaCourt.Fee
    End Class
End Namespace


Namespace PFD
    <Table("Fees", Schema:="PFD")>
    Public Class Fee
        Public Sub New()
            MyBase.New()
        End Sub

        Public Sub New(ByVal tFee As SOACourt_v1)
            Me.New()

            Me.Amount = tFee.Amount
        Me.DueDate = tFee.DueDate
        End Sub

        <Key>
        <ForeignKey("MetaData")>
        <DatabaseGenerated(DatabaseGeneratedOption.None)>
        Public Property FeeID As Int64

        ' Other domain-specific properties...

        Public Property MetaData As FeeMetadata
    End Class
End Namespace


Namespace SoaCourt
    <Table("Fees", Schema:="SoaCourt")>
    Public Class Fee
        Public Sub New()
            MyBase.New()
        End Sub

        Public Sub New(ByVal tFee As SOACourt_v1)
            Me.New()

            Me.CaseID = tFee.CaseID
            Me.CaseNumber = tFee.CaseNumber
            Me.TicketNumber = tFee.TicketNumber
        End Sub

        <Key>
        <ForeignKey("MetaData")>
        <DatabaseGenerated(DatabaseGeneratedOption.None)>
        Public Property FeeID As Int64

        ' Other domain-specific properties 

        Public Property MetaData As PFD.FeeMetadata
    End Class
End Namespace

EDIT:
Code to create and persist the database entities:

Using tContext As FeesContext = New FeesContext
    For Each tFee As SOACourt_v1 In tFees
        tContext.FeeMetadata.Add(New PFD.FeeMetadata(tFee))
    Next
    tContext.SaveChanges()
End Using

The problem I am having is that the SoaCourt.Fee entities are not being persisted to the database.
PFD.FeeMetadata and PFD.Fee are both saving properly, but SoaCourt.Fee is NOT.

Any thoughts on how to solve this?

Answer 1

The answer to this question is the solution here.

In summary: EF5 can not persist classes of the same name from different namespaces. Entity class names must be unique across namespaces.
