Can Dapper load a Multi-Mapping result when a join table is in use?

Question

I have an application object which has many connection objects. This is great in the .Net world but unfortunately the join is managed via a join table with a composite key. Is it possible to map this in dapper using a multi-mapping approach?

For now I am just using two seperate sql statements, but it doesn't sit well with me ( coming from the EF side of things ). Here is some code I tried but could not get to work...

public class Application
{
    public int ApplicationID { get; set; }
    public string Name { get; set; }
    public string Prefix { get; set; }

    public List<Connection> Connections { get; set; }
}

public class ApplicationConnection
{
    public int ApplicationID { get; set; }
    public int ConnectionID { get; set; }
}

public class Connection
{
    public int ConnectionID { get; set; }
    public string ConnectionString { get; set; }
}

var tsql = @"SELECT A.*,C.*
                        FROM [Application] A
                        INNER JOIN [ApplicationConnections] AC on A.ApplicationID = AC.ApplicationID
                        INNER JOIN [Connections] C ON AC.ConnectionID = C.ConnectionID
                        WHERE A.ApplicationID = 122";
            var results = connection.Query<Application, List<Connection>, Application>(tsql, 
                (appl, conn) => { 
                    appl.Connections = conn; return appl; 
                }, 
                splitOn: "ApplicationID,ConnectionID").First();

The error i keep getting is the "use splitOn" error, but I'm sure that is just the tip of the iceberg here. If anyone out there has any ideas, I'm all ears.
