+# RoslynBridge Extension Management Guide
+
+Quick reference for managing the RoslynBridge Visual Studio extension.
+
+## Common Issues
+
+### "Extension Already Installed" but Not Visible
+
+This happens when Visual Studio's extension cache is out of sync. Use the cleanup script:
+
+```powershell
+cd C:\Users\AJ\Desktop\RoslynBridge\RoslynBridge
+.\cleanup-and-reinstall.ps1
+```
+
+## Scripts
+
+### cleanup-and-reinstall.ps1
+
+Automates extension cleanup and reinstallation.
+
+**Basic Usage:**
+
+```powershell
+# Clean and reinstall everything (default)
+.\cleanup-and-reinstall.ps1
+
+# Only clean (remove extension and cache)
+.\cleanup-and-reinstall.ps1 -Action Clean
+
+# Only reinstall (skip cleanup)
+.\cleanup-and-reinstall.ps1 -Action Reinstall
+
+# Reinstall without rebuilding (use existing VSIX)
+.\cleanup-and-reinstall.ps1 -Action Reinstall -SkipBuild
+```
+
+**What it does:**
+
+1. **Closes Visual Studio** - Ensures no file locks
+2. **Cleans Cache** - Removes extension metadata cache
+3. **Removes Extension** - Deletes installed extension files
+4. **Rebuilds** - Compiles the extension in Release mode
+5. **Reinstalls** - Installs the new VSIX
+6. **Verifies** - Checks installation succeeded
+
+## Manual Management
+
+### Check if Extension is Installed
+
+```powershell
+# Check extension folder
+Test-Path "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ulxnn4r3.rql"
+
+# View extension files
+ls "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ulxnn4r3.rql"
+```
+
+### Manual Cleanup
+
+```powershell
+# Close Visual Studio first!
+
+# Remove cache files
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadataCache.sqlite" -Force
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadata.mpack" -Force
+
+# Remove extension
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ulxnn4r3.rql" -Recurse -Force
+
+# Remove component cache (optional, full reset)
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\ComponentModelCache" -Recurse -Force
+```
+
+### Manual Build
+
+```powershell
+cd C:\Users\AJ\Desktop\RoslynBridge\RoslynBridge
+
+# Build using MSBuild
+& "C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\MSBuild.exe" `
+    RoslynBridge.csproj `
+    /t:Rebuild `
+    /p:Configuration=Release `
+    /v:minimal
+```
+
+### Manual Install
+
+```powershell
+# Find the VSIX
+$vsixPath = (Get-ChildItem -Path . -Filter "*.vsix" -Recurse | Where-Object {
+    $_.FullName -like "*\bin\Release\*"
+} | Sort-Object LastWriteTime -Descending | Select-Object -First 1).FullName
+
+# Install using VSIXInstaller
+& "C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\VSIXInstaller.exe" `
+    /quiet `
+    /admin `
+    $vsixPath
+```
+
+## Testing the Extension
+
+### 1. Check Visual Studio Extensions UI
+
+1. Open Visual Studio
+2. Go to **Extensions → Manage Extensions**
+3. Click **Installed** tab
+4. Look for "Roslyn Bridge"
+
+### 2. Test HTTP Endpoint
+
+```powershell
+# Health check
+curl -X POST http://localhost:59123/health -H "Content-Type: application/json" -d "{}"
+
+# Get projects
+curl -X POST http://localhost:59123/query -H "Content-Type: application/json" -d '{"queryType":"getprojects"}'
+```
+
+### 3. Check Output Window
+
+In Visual Studio:
+1. Open **View → Output**
+2. Select "RoslynBridge" from the dropdown
+3. Should see startup messages when opening a solution
+
+### 4. Check Event Viewer (if issues)
+
+1. Open Event Viewer
+2. Navigate to: **Windows Logs → Application**
+3. Filter by Source: "VSPackage"
+4. Look for RoslynBridge-related messages
+
+## Debugging
+
+### Extension Won't Load
+
+**Symptoms:**
+- Extension shows in "Installed" but HTTP endpoint doesn't work
+- No output in RoslynBridge Output window
+
+**Solutions:**
+
+1. **Check Extension Loading:**
+   ```powershell
+   # In Visual Studio, open Developer PowerShell
+   Get-VSPackage | Where-Object { $_.Name -like "*Roslyn*" }
+   ```
+
+2. **Enable Diagnostic Logging:**
+   - Run Visual Studio with: `devenv.exe /log`
+   - Check log at: `%APPDATA%\Microsoft\VisualStudio\17.0_XXXXX\ActivityLog.xml`
+
+3. **Reset Visual Studio:**
+   ```cmd
+   devenv.exe /ResetSettings
+   ```
+
+### Port 59123 Already in Use
+
+```powershell
+# Check what's using the port
+netstat -ano | findstr :59123
+
+# Kill the process if needed
+taskkill /PID <PID> /F
+```
+
+### Extension Loads But Crashes
+
+Check the ActivityLog:
+```powershell
+# Open ActivityLog with formatting
+code "$env:APPDATA\Microsoft\VisualStudio\17.0_875bdf7a\ActivityLog.xml"
+```
+
+Look for entries with:
+- `Type="Error"`
+- `Source="RoslynBridge"`
+
+## Development Workflow
+
+### Quick Iteration During Development
+
+```powershell
+# 1. Make code changes
+
+# 2. Quick reinstall (no need to close VS manually)
+.\cleanup-and-reinstall.ps1
+
+# 3. Open Visual Studio and test
+```
+
+### Debugging the Extension
+
+1. Open the RoslynBridge solution in Visual Studio
+2. Set breakpoints in your code
+3. Press **F5** (or Debug → Start Debugging)
+4. This launches a new "Experimental Instance" of VS
+5. Open a solution in the experimental instance
+6. Breakpoints will hit in the original VS instance
+
+### Testing in Production VS (Not Experimental)
+
+```powershell
+# Install in production VS
+.\cleanup-and-reinstall.ps1
+
+# Attach debugger from another VS instance
+# 1. Open a second Visual Studio
+# 2. Debug → Attach to Process
+# 3. Select "devenv.exe" (the first VS)
+# 4. Set breakpoints in the RoslynBridge code
+```
+
+## Uninstalling
+
+### Complete Removal
+
+```powershell
+# Use the cleanup script
+.\cleanup-and-reinstall.ps1 -Action Clean
+
+# OR manually remove via Extensions Manager
+# 1. Open Visual Studio
+# 2. Extensions → Manage Extensions
+# 3. Find "Roslyn Bridge"
+# 4. Click "Uninstall"
+# 5. Restart Visual Studio
+```
+
+### Remove All Traces
+
+```powershell
+# Remove extension
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ulxnn4r3.rql" -Recurse -Force
+
+# Remove all VS caches (nuclear option)
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\ComponentModelCache" -Recurse -Force
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadataCache.sqlite" -Force
+Remove-Item "C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadata.mpack" -Force
+
+# Reset Visual Studio
+devenv.exe /ResetSettings
+```
+
+## Troubleshooting Quick Reference
+
+| Issue | Solution |
+|-------|----------|
+| Extension not visible in UI | `.\cleanup-and-reinstall.ps1` |
+| "Already installed" error | `.\cleanup-and-reinstall.ps1 -Action Clean` then reinstall |
+| Port 59123 not responding | Check extension loaded in Output window |
+| VS won't close | Use Task Manager to end `devenv.exe` |
+| Build fails | Check MSBuild output, ensure .NET SDK installed |
+| Install fails | Run as Administrator, check VSIXInstaller.exe exists |
+| Extension crashes on load | Check ActivityLog.xml for errors |
+
+## File Locations Reference
+
+```
+Extension Installation:
+C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ulxnn4r3.rql\
+
+Cache Files:
+C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadataCache.sqlite
+C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\Extensions\ExtensionMetadata.mpack
+C:\Users\AJ\AppData\Local\Microsoft\VisualStudio\17.0_875bdf7a\ComponentModelCache\
+
+Activity Log:
+C:\Users\AJ\AppData\Roaming\Microsoft\VisualStudio\17.0_875bdf7a\ActivityLog.xml
+
+Build Output:
+C:\Users\AJ\Desktop\RoslynBridge\RoslynBridge\bin\Release\
+
+VSIX File:
+C:\Users\AJ\Desktop\RoslynBridge\RoslynBridge\bin\Release\RoslynBridge.vsix
+```
+
+## Getting Help
+
+If issues persist:
+
+1. Check the ActivityLog.xml for detailed error messages
+2. Run Visual Studio with logging: `devenv.exe /log`
+3. Check Windows Event Viewer for crashes
+4. Try the "nuclear option": Complete removal + reinstall
+5. Check that .NET Framework 4.8 is installed
+6. Ensure Visual Studio 2022 Community/Pro/Enterprise (17.0+)
