1ms timer calling functions

Hi,
For testing purposes I have this timer that calls a function every 1ms and adds +1 to a counter. This code works perfectly fine as its calling windows native code but is there anything in the .NET framework even close to 1ms or shall I stick to using native calls?

Public Class Form1
    Dim mHandler As TimerEventHandler
    Dim iCount As Long = 0
    Dim mTimerId As Integer

    <DllImport("winmm.dll")>
    Private Shared Function timeSetEvent(delay As Integer, resolution As Integer, handler As TimerEventHandler, user As IntPtr, eventType As Integer) As Integer
    End Function

    <DllImport("winmm.dll")>
    Private Shared Function timeBeginPeriod(millisecond As Integer) As Integer
    End Function

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        timeBeginPeriod(1)
        mHandler = New TimerEventHandler(AddressOf TimerCallback)
        mTimerId = timeSetEvent(1, 0, mHandler, IntPtr.Zero, 1)
    End Sub

    Private Delegate Sub TimerEventHandler(id As Integer, msg As Integer, user As IntPtr, dw1 As Integer, dw2 As Integer)
    Private Sub TimerCallback(id As Integer, msg As Integer, user As IntPtr, dw1 As Integer, dw2 As Integer)
        iCount += 1
    End Sub
End Class
