Support building / deploying from a Network Drive

[dansiegel]

Describe the bug

When building an app with code located on a Network drive the app will fail to build/deploy

Steps to reproduce the bug

1. Create a new project using WindowsAppSdk on a network drive (i.e. on a Mac, or a NAS)
2. Open the project in Visual Studio
3. Attempt to build/run

Expected behavior

The app should build / run the same as it would if the code were located on the physical hard drive or primary VHD.
