Support building / deploying from a Network Drive

Nobody has claimed this yet.

### 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.

### Screenshots

**Packaged**

**Unpackaged**

### NuGet package version

Windows App SDK 1.5.1: 1.5.240311000

### Packaging type

Packaged (MSIX)

### Windows version

Windows 11 version 22H2 (22621, 2022 Update)

### IDE

Visual Studio 2022-preview, Visual Studio 2022

### Additional context

Note that the errors shown occur when creating a project using the WinUI template. Building an Unpackaged app from the Uno template actually does work.

No source files, tests, or entry points are named. Reproduce the packaged and unpackaged WinUI-template builds from a Windows network drive using Windows App SDK 1.5.1 and Visual Studio, then compare them with a local-drive build. Done means the app builds and runs from the network drive as it does from a physical drive or primary VHD.
