+Try this:
+class Singleton
+{
+  public static Singleton instance=null;
+  private Singleton() {
+  }
+  public static Singleton getInstance() {
+    if (instance==null) instance = new Singleton();
+    return instance;
+  }
+
+}
+
+class C
+{
+  static void Main ()
+  {
+	  Singleton s = new Singleton ();
+  }
+}
+
+instead of:
+class Singleton
+{
+  public static Singleton instance=null;
+  private Singleton() {
+  }
+  public static Singleton getInstance() {
+    if (instance==null) instance = new Singleton();
+    return instance;
+  }
+  static void Main ()
+  {
+	  Singleton s = new Singleton ();
+  }
+
+}
