I can no longer debug one of my projects. The build output window shows the following. I'm not exactly sure what has changed, but it used to debug fine. I didn't change the path, so I can't imagine how there are any illegal characters in it. Please let me know if there is any more information I can give.
```
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Node.js Tools\Microsoft.NodejsTools.targets(137,5): error MSB4018: The "AssignTargetPath" task failed unexpectedly.

```
Comments: It sounds like this is also the MAX_PATH issue that is floating around. I believe the problem started when I added gulp to devDependencies. I've moved my code to a really short folder name off of C:\ and it seems to be working again.
