Opening edmx file that is created in Entity Framework 5 in Entity Framework 4.4 RRS feed

  • Question

  • Hi,

    I have an edmx file that is created using .net Framework 4.5 and Entity Framework 5.0. I now wanted to open the same edmx file in .net framework 4.0 and Entity Framework 4.4.

    I am unable to see the designer, instead the xml file opens. Also when I run custom tool, I get the following error.

    "Could not find the storage model to validate."

    Please suggest me how to do this.

    Thanks,

    R. Venkatesan

  • Hello,

    The frameworks are not backward compatible; you can't edit newer EF versions with older tools. You have to create your model using EF 4
