…updates
**Root Cause:**
The UseOllama, UseOpenAI, UseClaude, and UseGemini properties were causing
infinite recursion through the ClearOtherProviders() method. When a RadioButton
was checked, it would trigger property changes that cascaded through all other
provider properties, causing WPF's TwoWay binding to create an infinite loop.
**Solution:**
Replaced the boolean backing fields with a single SelectedProvider property:
- Changed from 4 independent bool properties with mutual exclusion logic
- To computed properties based on SelectedProvider enum value
- Setters only update SelectedProvider when value is true
- Getters compare SelectedProvider to the enum value
- Single OnPropertyChanged notification for all 4 properties
**Technical Details:**
BEFORE:
```csharp
private bool _useOllama = true;
public bool UseOllama {
get => _useOllama;
set { if (SetProperty(ref _useOllama, value) && value)
ClearOtherProviders(nameof(UseOllama)); } // ❌ Triggers cascade
}
```
AFTER:
```csharp
private AIProvider _selectedProvider = AIProvider.Ollama;
public AIProvider SelectedProvider {
get => _selectedProvider;
set { if (SetProperty(ref _selectedProvider, value))
OnPropertyChanged for all 4 boolean properties; }
}
public bool UseOllama {
get => SelectedProvider == AIProvider.Ollama; // ✅ Computed
set { if (value) SelectedProvider = AIProvider.Ollama; } // ✅ No cascade
}
```
**Result:**
- No more circular property updates
- Clean single source of truth (SelectedProvider)
- RadioButton bindings work correctly
- StackOverflow exception eliminated

**Changes:** 1. **Exception Handler Guard** (App.xaml.cs): - Added _isHandlingException flag to prevent re-entry - Special handling for StackOverflowException (use Environment.FailFast) - Prevents infinite recursion when MessageBox.Show fails 2. **Diagnostic Logging** (App.xaml.cs + MainWindow.xaml.cs): - Added Debug.WriteLine at each initialization step - Tracks: service creation, DI configuration, database init, license check - Tracks: MainWindow construction, DataContext binding, navigation **Purpose:** These logs will help identify WHERE the StackOverflow is occurring: - If logs stop during "Building service provider" => DI circular dependency - If logs stop during "InitializeComponent" => XAML binding recursion - If logs stop during "Setting DataContext" => ViewModel property recursion - If logs stop during navigation => Page initialization issue **Next Step:** Run the app and check Debug Output to see exact failure point. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
**Root Cause:** The XAML parser was failing with: "FormatException: Llama is not a valid value for PackIconKind" This was happening in ContentGeneratorPage.xaml line 128, where the Ollama provider RadioButton was using a non-existent Material Design icon. **Fix:** Changed from: Kind="Llama" (doesn't exist) Changed to: Kind="Cpu64Bit" (valid CPU/processor icon) **Why This Appeared as StackOverflow:** The XAML parse exception was being caught by the global exception handler, which tried to show a MessageBox. The MessageBox itself triggered layout measurement, which tried to parse the same XAML again, creating an infinite loop that appeared as a StackOverflow. **Result:** - App should now start successfully - Ollama provider shows CPU icon (appropriate for local AI) - No more XAML parsing errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
**Error:** Line 154: "OpenaiChatgptApi is not a valid value for PackIconKind" **Fix:** Changed OpenAI provider icon from: - Kind="OpenaiChatgptApi" (doesn't exist) - To: Kind="Brain" (valid, represents AI/intelligence) **Icon Summary:** - Ollama: Cpu64Bit (local processing) - OpenAI: Brain (AI intelligence) - Claude: Chat (conversational AI) - Gemini: Google (Google's AI) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
**1. Real-time Status Updates (MainViewModel.cs):** - Changed from 30 seconds → 1 second interval - Users see AI status changes immediately - Better user experience for debugging **2. Enhanced Ollama Status Check (OllamaContentGenerator.cs):** BEFORE: Only checked if Ollama is running NOW: 3-step verification: ✅ Step 1: Check if Ollama service is running (GET /api/tags) ✅ Step 2: Verify model (llama3.2) is installed ✅ Step 3: Return detailed status message **Status Messages:** - ✅ "Ollama ready (llama3.2)" - All good - ❌ "Ollama is not running" - Service offline - ❌ "Model 'llama3.2' not installed. Run: ollama pull llama3.2" -⚠️ "Ollama timeout - not running" - Connection timeout (2s) -⚠️ "Cannot connect: [error]" - Network/other error **3. Detailed Error Display (MainViewModel.cs):** - Shows specific error messages from providers - Example: "ไม่พร้อม - Model 'llama3.2' not installed. Run: ollama pull llama3.2" - Helps users understand exactly what's wrong **Why This Matters:** Before: User sees "พร้อม" but AI Content fails silently After: User sees exact problem and how to fix it **Technical Details:** - Added 2-second timeout for status checks - Added OllamaTagsResponse/OllamaModel DTOs - Parse model list from /api/tags response - Check if required model exists in installed models 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
**Problem:**
AI Status showed "ไม่พร้อม - ไม่มี AI Provider" even though Ollama was installed.
**Root Cause:**
AIContentService.InitializeProvidersAsync() was never called during app startup,
so the _generators dictionary was empty. The status check tried to iterate over
an empty dictionary and found no providers.
**Solution:**
Added AI provider initialization to App.OnStartup() after database initialization:
```csharp
// Initialize AI providers
System.Diagnostics.Debug.WriteLine("App: Initializing AI providers...");
var aiService = Services.GetRequiredService<Core.Services.AI.AIContentService>();
await aiService.InitializeProvidersAsync();
```
**Initialization Flow (Fixed):**
1. ✅ Configure DI container
2. ✅ Initialize database
3. ✅ **Initialize AI providers** ← NEW!
4. ✅ Check license status
5. ✅ Create MainWindow
6. ✅ Start 1-second AI status monitoring
**What InitializeProvidersAsync() Does:**
- Reads Ollama URL from settings (default: http://localhost:11434)
- Creates OllamaContentGenerator with model "llama3.2"
- Reads API keys for OpenAI, Claude, Gemini
- Creates generators only for configured providers
- Logs: "Initialized {Count} AI providers"
**Result:**
- ✅ Ollama will be detected on startup
- ✅ Status will show: "พร้อม (Ollama)" or detailed error
- ✅ Real-time monitoring works correctly

🔴 Provider: Ollama
🔴 Error: [actual error message]
💡 แนะนำ:
1. ตรวจสอบว่า Ollama กำลังรันอยู่ (ollama serve)
2. ตรวจสอบว่าติดตั้ง model แล้ว (ollama pull llama3.2)
3. ตรวจสอบ AI Status ที่ Status Bar ด้านล่าง
```
**Debug Logging:**
- Added: "Attempting to generate content with provider: {provider}"
- Added: "✅ Content generated successfully using {result.Provider}"

2. ✅ Users see exact error message
3. ✅ Users get step-by-step troubleshooting guide
4. ✅ Developers can debug from Debug Output window
**Common Scenarios:**
| Scenario | Error Message | Solution |
|----------|---------------|----------|
| Ollama not running | "Cannot connect: ..." | Run: `ollama serve` |
| Model not installed | "Model 'llama3.2' not installed..." | Run: `ollama pull llama3.2` |
| Network timeout | "Ollama timeout - not running" | Check if Ollama is running |
| Wrong port | "Cannot connect: ..." | Check Ollama URL in Settings |

**Problem:**
When content generation failed, error showed:
"Error: All AI providers failed. Please check your settings."
This didn't help users understand the REAL problem with Ollama.
**Root Cause:**
AIContentService.GenerateContentAsync() tried fallback providers and when
all failed, returned generic "All AI providers failed" message, losing the
original Ollama error details.
**Solution:**
Track errors from each provider and return the FIRST error (from preferred
provider) which is most relevant:
```csharp
string? firstError = null;
var errors = new List<string>();
// Try preferred provider
var result = await generator.GenerateContentAsync(request, cancellationToken);
if (!result.Success)
{
firstError = result.ErrorMessage; // ✅ Save the real error!
errors.Add($"{preferredProvider}: {result.ErrorMessage}");
}
// ... try fallbacks ...
// Return first error (most relevant)
return new ContentGenerationResult
{
Success = false,
ErrorMessage = firstError ?? "No AI providers available",
Provider = preferredProvider
};
```
**Now Users Will See:**
```
🔴 Provider: Ollama
🔴 Error: Cannot connect to Ollama: Connection refused
```
Instead of:
```
🔴 Error: All AI providers failed
```
**Also Handles:**
- Provider not initialized: "Provider Ollama not initialized"
- No providers: "No AI providers available"
- Actual Ollama errors: Connection refused, timeout, model not found, etc.
**Debugging:**
Added detailed logging for each fallback attempt to help track which
providers were tried and why they failed.

3. HTTP status code analysis with detailed error messages
4. Model availability verification (OpenAI, Gemini)
- Provider-specific error messages:
- OpenAI: Invalid key, rate limit, server errors, model availability
- Claude: Invalid key, rate limit, overloaded status
- Gemini: Invalid key format, auth errors, safety filters
- Network error handling (HttpRequestException, TaskCanceledException)
**Enhanced Content Generation (All Providers):**
- Debug logging for all operations:
- [Provider] Generating content for topic: {topic}
- [Provider] ✅ Content generated successfully ({tokens} tokens)
- [Provider] ❌ {error message}
- Detailed error categorization:
- Network errors
- Timeout errors
- HTTP status codes (401, 403, 429, 500, 503)
- Provider-specific errors (Claude overloaded, Gemini safety)
- User-friendly error messages with actionable information
**New Models:**
- OpenAIModelsResponse + OpenAIModel (for model verification)
- GeminiModelsResponse + GeminiModel (for model verification)
**Benefits:**

**Problem:**
- User reported Error 404 when generating content
- Generic error messages didn't show which provider or what went wrong
- Gemini model 'gemini-2.0-flash-exp' may not be available (404)
**Solution:**
1. **Enhanced HTTP Error Handling (All Providers):**
- Added error body reading before throwing exceptions
- Show detailed HTTP status code + response body in Debug output
- Provider-specific error messages:
- OpenAI 404: "Model not found or not available"
- Claude 404: "Model not found or endpoint incorrect"
- Claude 529: "Claude is overloaded - try again later"
- Gemini 404: "Model not found. Try 'gemini-pro' or 'gemini-1.5-flash'"
2. **Request Debugging:**
- [OpenAI] Shows model being requested
- [Claude] Shows model being requested
- [Gemini] Shows sanitized URL (API key hidden)
- [Provider] HTTP {code} Error: {body} when request fails
3. **Gemini Model Fix:**
- Changed from 'gemini-2.0-flash-exp' → 'gemini-1.5-flash' (stable)
- Updated both AIContentService and GeminiContentGenerator default
