title: Visual Studio Cant Find File - Debugging
body: <p>During debugging in Visual Studio 2015 it cant find files:</p>
  
  <pre><code>xxxx.cs not found
  You need to find xxx.cs to view the source for the current call stack frame
  
  Try one of the following options:
  - Browse and find xxx.cs
  
  You can view disassembly in the Dissasembly window. To alsways view dissassembly for the missing source files, change the setting in the Options dialog
  </code></pre>
  
  <p>The .cs file in question is from a third party dll, so I do not expect to be able to step through it. It seems to be acting as though I am not in debug, but I am, and I have  in the web.config. I have tried a million settings in VS, but nothing seems to help. For example:</p>
  
  <p>Enable Just My Code is unchecked
  Adding the files to the 'Do not look for these source files' list makes it stop asking where file is, but I still get the 'xxx.cs not found' tab</p>
