Using mvc-mini-profiler with EF 4.0 and Ninject

Question

I\'m trying to use the new mvc-mini-profiler with my EF4 based app, but I have no idea how to properly get a connection to my destination datasource.

Here\'s as far as I

Answer 1

Slightly less hacky way:

private static SqlConnection GetConnection()
{
    var connStr = ConfigurationManager.ConnectionStrings["ModelContainer"].ConnectionString;
    var entityConnStr = new EntityConnectionStringBuilder(connStr);
    return new SqlConnection(entityConnStr.ProviderConnectionString);
}

Amendment by John Gietzen:

This combination of all of the answers should work for ANY backing store that Entity Framework supports.

public static DbConnection GetStoreConnection() where T : System.Data.Objects.ObjectContext
{
    return GetStoreConnection("name=" + typeof(T).Name);
}

public static DbConnection GetStoreConnection(string entityConnectionString)
{
    // Build the initial connection string.
    var builder = new EntityConnectionStringBuilder(entityConnectionString);

    // If the initial connection string refers to an entry in the configuration, load that as the builder.
    object configName;
    if (builder.TryGetValue("name", out configName))
    {
        var configEntry = WebConfigurationManager.ConnectionStrings[configName.ToString()];
        builder = new EntityConnectionStringBuilder(configEntry.ConnectionString);
    }

    // Find the proper factory for the underlying connection.
    var factory = DbProviderFactories.GetFactory(builder.Provider);

    // Build the new connection.
    DbConnection tempConnection = null;
    try
    {
        tempConnection = factory.CreateConnection();
        tempConnection.ConnectionString = builder.ProviderConnectionString;

        var connection = tempConnection;
        tempConnection = null;
        return connection;
    }
    finally
    {
        // If creating of the connection failed, dispose the connection.
        if (tempConnection != null)
        {
            tempConnection.Dispose();
        }
    }
}
