title: Visual Studio 2015 Getting Method add_PropertyChanged in type Namespace_Accessor from assembley does not have implementation
body: <p>I am working on a webform application which I migrated with <code>Visual Studio 2015</code> from 4.6.</p>
  
  <p>I am getting the following error:</p>
  
  <p><code>Method 'add_PropertyChanged' in type Namespace_Accessor from assembly does not have an implementation</code></p>
  
  <p>I also getting <code>The BuildShadowTask task failed unexpectively</code></p>
  
  <p>I did a search for <code>add_PropertyChanged</code> nothing shows up.</p>
  
  <p>The Namespace, I found in the WindowService. When I clicked on the Service Reference and when I clicked on any of the property, it takes me to the Reference.cs file. I do see this in the code</p>
  
  <p><code>public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;</code></p>
  
  <p>THe <code>class</code> inherits from <code>System.ComponentModel</code> and see the following as part of the interface <code>INotifyPropertyChanged</code></p>
  
  <p><code>event PropertyChangedEventHandler PropertyChanged;</code></p>
  
  <p>I googled this issue and people are getting this error because private accessor are deprecated in 2010 and will not build in 2015.</p>
  
  <p>They say remove private via reflection but I am not sure how to do this.</p>
  
  <p>I read an article which looks a lot like my problem but it did not give any details on how to fix this bug. </p>

  <p>Any help is greatly appreciate to get this build without this error.</p>
  
  <p>Thanks</p>
