title: Trying to run an Azure Function App locally from Visual Studio 2017 gives a 'func.exe does not exist' error
body: <p>I have created a new Azure Function app with an Http Trigger in Visual Studio 2017 (which I have just updated to v15.8.4).
  Using the generated function, when I try to run it I just get a message box with the error</p>
  
  <pre><code>The debug executable "C:\Users\Paul\AppData\Local\AzureFunctionTools\Releases\2.5.2\cli\func.exe" specified in the 'FunctionApp1' debug profile does not exist.
  
  Sure enough there is no func.exe at that location, just a func.dll.
  
  The file C:\Users\Paul\AppData\Local\AzureFunctionTools\Releases\1.3.0\cli\func.exe does exist.
  </code></pre>
  
  <p>I have successfully run an Azure function locally before but I assume updating Visual Studio a few times has broken something.
  How can I get this working?</p>
