Windows: Sound not playing - missing PresentationCore assembly

[akshay1845]

Bug Description

The extension doesn't play sound on Windows because the PowerShell command is missing the required PresentationCore
assembly import.

Environment

• OS: Windows
• Extension Version: 0.0.4

Root Cause

In dist/extension.js (line 103), the Windows sound playback command is:

cmd = `powershell -c "$p = New-Object System.Windows.Media.MediaPlayer; $p.Open('${filePath}'); $p.Play(); Start-Sleep  
3"`;

The System.Windows.Media.MediaPlayer class requires the PresentationCore assembly to be loaded first.

Error

When the extension tries to play sound, PowerShell throws:
Cannot find type [System.Windows.Media.MediaPlayer]: verify that the assembly containing this type is loaded.

Fix

Add Add-Type -AssemblyName PresentationCore; before creating the MediaPlayer object:

cmd = `powershell -c "Add-Type -AssemblyName PresentationCore; $p = New-Object System.Windows.Media.MediaPlayer;        
$p.Open('${filePath}'); $p.Play(); Start-Sleep 3"`;

This fix has been tested and confirmed working on Windows.
