WinForms designer error variable is undeclared or unassigned

Question

My windows form application form form is giving an error when i change to design mode in visual studio 2015.

It says "The variable 'componentResourceManager' is either undeclared or was never assigned. "

Here is the line with the error

 

this.pictureBox1.Image = (Image) componentResourceManager.GetObject("pictureBox1.Image");


and here is how i initialized the resourcemanager

private void InitializeComponent()
    {
      this.components = (IContainer) new Container();
      ComponentResourceManager componentResourceManager = new ComponentResourceManager(typeof (frmMainMDI));

But when i run the application all the forms load well.What could be the problem?
