Can't debug

Debugging is enabled in web.config but the program isn't halting at breakpoints. For instance, I set a breakpoint in this sub but the program just finished loading the page without pausing.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


Dim myConnectionString As String
myConnectionString = "blah"

Dim myConnection As New MySqlConnection(myConnectionString)
Dim myQuery As String = "SELECT * from blah ORDER BY blah asc"
Dim myCommand As New MySqlCommand(myQuery)

myConnection.Open()
myCommand.ExecuteNonQuery()
myCommand.Connection.Close()
myConnection.Close()
