# Install-TfsShell & Uninstall-TfsShell Implementation Summary
2+
3+
## Overview
4+
This implementation adds two new cmdlets to TfsCmdlets that provide shell installation management with Windows Terminal support.
5+
6+
## Files Added/Modified
7+
8+
### New C# Cmdlets
9+
- `CSharp/TfsCmdlets/Cmdlets/Shell/InstallShell.cs` - Install-TfsShell cmdlet implementation
10+
- `CSharp/TfsCmdlets/Cmdlets/Shell/UninstallShell.cs` - Uninstall-TfsShell cmdlet implementation
11+
12+
### Windows Terminal Profile Fragments
13+
- `PS/AzureDevOpsShell-WinPS.json` - Windows PowerShell profile for Windows Terminal
14+
- `PS/AzureDevOpsShell-PSCore.json` - PowerShell Core profile for Windows Terminal
15+
16+
### Enhanced WiX Installer
17+
- `Setup/Product.wxs` - Updated with Windows Terminal detection and conditional shortcut creation
18+
19+
### Documentation
20+
- `CSharp/TfsCmdlets/Cmdlets/Shell/Install-TfsShell.md` - Cmdlet documentation
21+
- `CSharp/TfsCmdlets/Cmdlets/Shell/Uninstall-TfsShell.md` - Cmdlet documentation
22+
- `CSharp/TfsCmdlets/Cmdlets/Shell/index.md` - Updated index with new cmdlets
23+
24+
### Tests
25+
- `PS/_Tests/Shell/InstallUninstallTfsShell.Tests.ps1` - Pester tests for new cmdlets
26+
- `PS/_Tests/Shell/ManualValidationTest.ps1` - Manual validation script
27+
28+
## Key Features
29+
30+
### Install-TfsShell Cmdlet
31+
- **Windows Terminal Detection**: Automatically detects if Windows Terminal is installed
32+
- **Conditional Shortcut Creation**: Creates WT shortcuts if detected, PowerShell shortcuts otherwise
33+
- **Profile Installation**: Deploys WT profile fragments to the user's settings
34+
- **Target Support**: Supports StartMenu, Desktop, and WindowsTerminal targets
35+
- **Force Parameter**: Allows forcing PowerShell shortcuts even when WT is detected
36+
37+
### Uninstall-TfsShell Cmdlet
38+
- **Shortcut Removal**: Removes shortcuts from all known locations
39+
- **Profile Cleanup**: Removes Windows Terminal profile fragments
40+
- **Target Support**: Supports selective removal by target
41+
42+
### Windows Terminal Integration
43+
- **Profile Fragments**: JSON files for both Windows PowerShell and PowerShell Core
44+
- **Automatic Detection**: Registry and file system checks for wt.exe
45+
- **Settings Deployment**: Copies profiles to WT settings directory
46+
47+
### Enhanced WiX Installer
48+
- **Registry Search**: Detects Windows Terminal via App Paths registry
49+
- **Conditional Components**: Two mutually exclusive shortcut components
50+
- **Backward Compatibility**: Falls back to PowerShell shortcuts when WT not detected
51+
52+
## Usage Examples
53+
54+
```powershell
55+
# Install with default targets (StartMenu + Desktop)
56+
Install-TfsShell
57+
58+
# Install only to Start Menu
59+
Install-TfsShell -Target StartMenu
60+
61+
# Force PowerShell shortcuts even if Windows Terminal is detected
62+
Install-TfsShell -Force
63+
64+
# Remove from all locations
65+
Uninstall-TfsShell
66+
67+
# Remove only Windows Terminal profiles
68+
Uninstall-TfsShell -Target WindowsTerminal
69+
```
70+
71+
## Implementation Notes
72+
73+
1. **C# Architecture**: Uses the existing TfsCmdlets pattern with ControllerBase inheritance
74+
2. **Cross-Platform Aware**: Handles non-Windows environments gracefully
75+
3. **Error Handling**: Comprehensive try-catch blocks with logging
76+
4. **PowerShell Integration**: Uses PowerShell service for shortcut creation via COM
77+
5. **Registry Safe**: Handles registry access failures gracefully
78+
6. **Path Validation**: Validates all paths before operations
79+
80+
## Compatibility
81+
82+
- **Existing Shortcuts**: Compatible with existing chocolatey and WiX installer shortcuts
83+
- **Chocolatey**: Existing chocolatey scripts remain unchanged for compatibility
84+
- **Windows Terminal**: Supports both Windows PowerShell and PowerShell Core profiles
85+
- **Legacy Systems**: Falls back to PowerShell shortcuts when WT is not available
86+
87+
## Testing
88+
89+
- **JSON Validation**: Verified JSON profile syntax and content
90+
- **Cross-Platform Logic**: Tested detection logic simulation on Linux
91+
- **Pester Tests**: Basic cmdlet availability and parameter validation
92+
- **Manual Validation**: Comprehensive logic testing script
93+
94+
## Future Enhancements
95+
96+
1. **Chocolatey Integration**: Could update chocolatey scripts to use new cmdlets
97+
2. **Taskbar Support**: Could add Windows Taskbar shortcut support
98+
3. **Profile Customization**: Could allow custom profile names/settings
99+
4. **Multiple Profiles**: Could support installing multiple profile variants
