 ## Remarks  
  When you assign a new value to the <xref:System.Threading.WaitHandle.SafeWaitHandle%2A> property, the previous handle will be closed when the previous <xref:Microsoft.Win32.SafeHandles.SafeWaitHandle> object is collected. Do not manually close the handle, because this results in an <xref:System.ObjectDisposedException> when the <xref:Microsoft.Win32.SafeHandles.SafeWaitHandle> attempts to close the handle.  
   
- <xref:System.Threading.WaitHandle> implements the <xref:System.IDisposable.Dispose%2A> pattern. See [Implementing a Dispose method](~/docs/standard/garbage-collection/implementing-dispose
-.md). When you derive from <xref:System.Threading.WaitHandle>, use the <xref:System.Threading.WaitHandle.SafeWaitHandle%2A> property to store your native handle operating system handle. You do not need to override the protected <xref:System.Threading.WaitHandle.Dispose%2A> method unless you use additional unmanaged resources.
