Windows form doesn't close after close?

I made a very simple program, but when I close it using the red X at the top right, I can still see it in the Windows Task Manager listed under processes. The program is still running and consuming memory. How can I avoid this?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework;

namespace PS3Controller
{
public partial class Form1 : Form
{
    GamePadState pad;

    Vector2 centroIzq = new Vector2(138, 132);
    Vector2 centroDer = new Vector2(139, 252);

    float distancia = 20f;

    float ledIzqAngulo = 0;
    float ledDerAngulo = 0;

    float ledIzqVelocidad = 0.0022f;
    float ledDerVelocidad = 0.0022f;


    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        pad = GamePad.GetState(Microsoft.Xna.Framework.PlayerIndex.One);

        if (pad.Buttons.Y == Microsoft.Xna.Framework.Input.ButtonState.Pressed)
            ledTtriangulo.Visible = true;
        else
            ledTtriangulo.Visible = false;

        if (pad.Buttons.X == Microsoft.Xna.Framework.Input.ButtonState.Pressed)

Are you sure its your app that is still running or is it YourApp.vshost.exe? The vshost is for Visual Studio and will always run while you have your project open.

Be sure to close all the thread of that process...Sometime, the thread keep process to keep executing though the form is closed...You can do this in OnClosing method of windows form......
