.NET Quick Start project and local database/MDF working on localhost but giving exceptions on remote server?

Question

I am running dot quick start project locally perfectly with following connection. However i don't the location on which its creating the mdf file.

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-mirror-quickstart-dotnet-20130523105156;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-mirror-quickstart-dotnet-20130523105156.mdf" />

I have checked app_data its empty.

Anyways when i upload this project on remote server as soon as I click Accept button displaying on google authorization page it throws following exception.

[Win32Exception (0x80004005): The system cannot find the file specified]

To solve above I did try to modify connectionstring with same name "DefaultConnection" but with integrated security. But exception stays the same. Local copy which is not giving exception and seems to work also confuses me because i dont know the database location it used to store user credentials.

Answer 1

Basically instead of using connection string that was consuming development based express database server. I have provided connection to sql server 2012 instance. For that I had to make few changes in web.config and global.asax.cs file.

inside web.config you have to change entityframework section and make sure you use sqlconnection (System.Data.Entity.Infrastructure.SqlCeConnectionFactory) instead of local connection.

Since this code is taken from google team they were also using connection inside global.asax.cs file so i had made changes there as well.

One important point make sure your connectstring dont use integrated security instead provide username and password for connection. that is required because entity framework will try to create new database. User that you are providing in datbase connection should have roles/permission to creates database.

web.config

<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
  <parameters>    
  <parameter value="Data Source=.\someserver; Integrated Security=False; User ID=myuser;Password=mypass; MultipleActiveResultSets=True" />
  </parameters>
</defaultConnectionFactory>
<providers>
  <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>


<clear />
<remove name="DefaultConnection" />

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=.\someserver;database=mydb;Integrated Security = False; User ID=myuser; Password=mypass;"/>

Global.asax.cs

protected void Application_Start() { AreaRegistration.RegisterAllAreas();

        Database.DefaultConnectionFactory = new SqlConnectionFactory(@"Data Source=.\someserver; Integrated Security=False;User ID=myuser;Password=mypass; MultipleActiveResultSets=True");

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);
    }
