Datagridview and generic list

My task class exposes a developer object
    Public Property Developer() As Developer
        Get
            Return mDeveloper
        End Get
        Set(ByVal value As Developer)
            mDeveloper = value
        End Set
    End Property


How can I access this while binding?

This is what I have tried and it does not display the full name.

dgvTasks.AutoGenerateColumns = False

Dim list As New List(Of Task)
Dim task As New Task()
list = task.GetTasks(projectID)

dgvTasks.DataSource = list
dgvTasks.Columns.Add("Description", "Description")
dgvTasks.Columns.Add("FullName", "Developer")

dgvTasks.Columns(0).DataPropertyName = "Description"
dgvTasks.Columns(1).DataPropertyName = "Developer.FullName"
