Question

I am using Entity Framework 4 with my Asp.Net MVC3 application. My problem is that I am using Entity Framework to perform action with my database , That i

Answer 1

Theres a better solution here, use the Entity Framework Power tools, reverse engineer your database into your project, then you can use a single EF connection string (which is a normal connection string) for both scenarios.

Answer 2

The connection string for ADO.NET (in this case SqlConnection) doesn't take that format. You're using the one specific for Entity Framework. The ADO.NET one should be something like:

"data source=KAPS-PC\KAPSSERVER;initial catalog=vibrant;integrated security=True"

So, to sum it up, you need two separate connection strings, one for EF and one for ADO.NET

Answer 3

Another option (other than 2 separate connection strings for the same thing) is to build a method that returns an ADO.NET connection string from your Entity Framework object:

using System.Data.EntityClient;
using System.Data.SqlClient;
...
private string GetADOConnectionString()
{
    SalesSyncEntities ctx = new SalesSyncEntities(); //create your entity object here
    EntityConnection ec = (EntityConnection)ctx.Connection;
    SqlConnection sc = (SqlConnection)ec.StoreConnection; //get the SQLConnection that your entity object would use
    string adoConnStr = sc.ConnectionString;
    return adoConnStr;
}

(I place this somewhere in my Class Library where my edmx files are)

Or even better... if your SQLConnection stuff are manual SQL queries, skip the SQLConnection entirely via the ExecuteStoredCommand:

new AdventureEntities().ExecuteStoreCommand(
        @"    UPDATE Users
              SET lname = @lname 
              WHERE Id = @id",
        new SqlParameter("lname", lname), new SqlParameter("id", id));

(I got this from Entity Framework getting an sql connection)

Answer 4

You connection string is specific to Entity Framework and contains metadata. You need to get your provider connection string from it. You can do it using EntityConnectionStringBuilder:

var efConnectionString = "Your Entity Framework connection string";
var builder = new EntityConnectionStringBuilder(efConnectionString);
var regularConnectionString = builder.ProviderConnectionString;
