We use Entity Framework 5, but have a requirement to ALSO use a normal database connection from the application for some custom SQL we need to perform.

Here's how to get the connection string in EF 5, EF 6 and EF Core 1/EF 7.
//Entity Framework 5
myContext.Database.Connection.ConnectionString
//Entity Framework 6
myContext.Database.Connection.ConnectionString
//Entity Framework Core 1
myContext.Database.GetDbConnection().ConnectionString
