I am using Entity Framework in my projects. First I do the following:

  1. Start Visual Studio
  2. Select Project >> Add New Items >> Ado.Net Entity Data Model
  3. Select Generate From Database and Next
  4. Click New Connection Button And Connect To Oracle
  5. Connect
  6. Finish

Then I Disconnect From Oracle Server:

  1. In Visual Studio
  2. Project >> Add New Items >> Ado.Net Entity Data Model
  3. Select Generate From Database and Next

Then the Oracle Connection Wizard opened automatically, and I closed the connection dialog box, and the Entity Framework Wizard closed immediately. I cannot connect to any server after this step.

Hard to tell what you mean. Can you describe step-by-step which actions you do, using names of buttons/menu items? - Gert Arnold
Ah. Much better! But could you generate a new model at all without database connection? I think in that case you can only create an empty model ("Empty Model" in stead of "Generate From Database"). - Gert Arnold
YES, Thank you. This is a Wizard Bug. in Empty Model i can Right Click And Select Update Model. - mehr
To resolve this issue I have made these step and it solved Entity Data Model wizard disappears Issue - Umang Patwa

I don't know if this is your problem, but I've had similar issues (Visual Studio crashed when I open a file). Try deleting the .suo file in the main folder of your project and see.

Visual studio wizard picks automatically the first connection listed on data connections when you open the database explorer.

If you delete/update the first connection then the new connection will automatiaclly appear on the wizard. If you del all connections the wizard won't automatically display that stupid dialog box.

You can create an empty model, then in the Model Browser or explorer properties for file.edmx right-click Model.edmx or YourModel.edmx. Choose Update Model From Database.

This way is similar to creating the model from database using ado.net..
