Migrating from VS 2012 to VS 2015 Community

When I try to open up my C# ASP.Net pages using VS 2015 Community in Design View it gives me an error saying it cannot find the master page.  It does this for all pages.  The pages display properly online.  Pages do load and display properly in Desgin View when using VS 2012 Developer.

When looking at source code the MasterPageFile path is highlighted with tool tip saying file not found.
Page Title="" Language="C#" MasterPageFile="~/MenuLHE001.master" AutoEventWireup="true" CodeFile="CompanyFind1.aspx.cs" Inherits="admin_CCalls"

Any thoughts what would cause this error for all pages?

Thank you
