Answer 1

My LocalDB was deleted. I recreate it and my project now is running successfully. Thank you all to support me.

Answer 2

please use the correct connection string as provided in the tutorial:

<add name="MovieDBContext" 
   connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Movies.mdf;Integrated Security=True" 
   providerName="System.Data.SqlClient" 
/> 

It is likely a problem with your authentication with the user sa.

//Update

I have just installed VS 2013 on my DevVM (Server 2008R2) I created an Asp.Net MVC 5 project and used nuget to add Entity Framework to the project. After this I created the models and added the connectionstring to the web.config Then I clicked controlles -> add -> scaffold, choose the model data context and name, hit add and then run the project. Works like a charm. All CRUD functionality is working.

  public ActionResult Index()
                {
                    List<EmployeeDetail> employees = context.EmployeeDetails.ToList();
                    List<Employee> emp = new List<Employee>();
                    foreach(EmployeeDetail item in employees)
                    {
                        emp.Add(new Employee
                            {
                                ID=Convert.ToInt32(item.ID),
                                Branch=item.Branch,`enter code here`
                                Salary=Conve`enter code here`rt.ToInt32(item.Salary),
                                UID = Convert.ToInt32(item.ID),
                            });
                    }
                    return View(emp);
                }

Answer 4

I believe this is caused by 2 connection strings...had the same problem and getting rid of one helped.

Answer 5

Take care that you may also have some user.config files that have strayed into the path of being picked up by your application

C:\Users\USERNAME\AppData\Local\PROJECTNAME_vs_Url_a2dblg5lbsfkc1adurpcald1inggdlg1\

Answer 6

do not use "." to define the dbserver. use the full machine name
