Hey Imar,

If I follow your example on page 481/482 adding an 'Entity Data Model file', starting with the code snippet on page 482, in my own site i get an error saying:"'Using' operand of type 'VacaturesModel.VacaturesEntities' must implement 'System.IDisposable'." Where the f#ck did I go wrong????

I put the 'imports VacatureModel' in the code behind file, the Entity Data Model file was created following the prior steps, I cannot find a mistake I made...
Code inside 'Using' statement is missing in snippet below...

Code:

Imports VacaturesModel

Partial Class Vacatures_VacaturesTotaal
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Using myEntities As New VacaturesEntities()

        End Using
    End Sub
End Class

Hi Bertus,

Does the model look OK to you? That is, do you get IntelliSense on the entities variable? Maybe you gave a different name to the model? To check, open the model's designer, click somewhere on the diagram and look at the Properties window.

Also, check for other errors in the Error List.

If all of this fails, can you send me a copy of the site? If you send me a message through my site at http://imar.spaanjaars.com, I'll reply so you have my email address.

Met vriendelijke groeten ;-)

Imar'
