I've always done web apps and now I need to do a console app. I need to use both an odbc connection and a regular connection. 

In the past I would have used:

```
<add name="LinkConnectionString" connectionString="Data Source=SERENITY\SQLEXPRESS;Initial Catalog=Link;Integrated Security=True" providerName="System.Data.SqlClient"/>

```

In the web.config, however I am not sure how to do the same thing with inline code. 
So like string connectionString = @".....";

I have tried multiple combinations, looked online (including connectionstrings.com), but none of them worked. 

Can anyone help me out? I want both the odbc and the regular... as they seem different should be different according to the sample ones online (that don't work).
