# .NET 8 Upgrade Progress - Crestron Mocking

## Current Status (August 13, 2025)

### ✅ Completed Tasks
1. **Namespace Migration**: Successfully migrated 26+ files from `Crestron.SimplSharp.CrestronIO` to `System.IO`
2. **Main Projects Building**: All main solution projects (PepperDash.Essentials, PepperDash.Essentials.Core, etc.) are building successfully for .NET 8
3. **CrestronMock Project Structure**: Established comprehensive mock structure with proper namespace hierarchy
4. **Duplicate Definition Resolution**: Resolved 37+ duplicate type definition errors by cleaning up conflicting files
5. **HTTP/HTTPS Client Mocks**: Implemented complete HTTP/HTTPS client mocks with proper instance-based architecture
6. **Core Networking Mocks**: Basic TCP/UDP client/server mock implementations created

### 🔄 In Progress - PepperDash.Core Test Configuration
Currently working on making PepperDash.Core build successfully with Test configuration using CrestronMock implementations.

#### Recent Progress:
- ✅ Removed duplicate WebAndNetworking_New.cs file (eliminated 37 duplicate errors)
- ✅ Cleaned duplicate type definitions from Extensions.cs
- ✅ Implemented comprehensive HTTP/HTTPS client mocks with proper method signatures
- ✅ Added missing TCP client properties and methods (LocalPortNumberOfClient, callback overloads)
- 🔄 **Currently fixing**: TCPServer missing _bufferSize field and additional constructor overloads

#### Last Action Taken:
Working on TCPServer.cs - added 2-parameter constructor but need to add missing `_bufferSize` private field.

### 🎯 Immediate Next Steps
1. **Fix TCPServer.cs**:
   - Add missing `private int _bufferSize;` field
   - Add missing event handler properties (SocketStatusChange)
   - Add missing method overloads for SendDataAsync/ReceiveDataAsync

2. **Complete Remaining Mock Types**:
   - UDPServer properties (IPAddressLastMessageReceivedFrom, IPPortLastMessageReceivedFrom, IncomingDataBuffer)
   - SecureTCPServer/SecureTCPClient missing methods
   - CrestronQueue.TryToEnqueue method
   - ProgramStatusEventHandler delegate
   - Console command response methods

3. **System Types & Environment**:
   - InitialParametersClass properties (ApplicationNumber, RoomId, RoomName, etc.)
   - CrestronEnvironment methods (Sleep, OSVersion, GetTimeZone, etc.)
   - CrestronDataStoreStatic methods (InitCrestronDataStore, SetLocalIntValue, etc.)
   - IPAddress type and related networking types

### 📊 Build Status
- **Main Projects**: ✅ All building successfully for .NET 8
- **PepperDash.Core Test Config**: ❌ Multiple compilation errors (see below)
- **Error Count**: ~150+ compilation errors remaining (down from 200+)

### 🚨 Key Error Categories Remaining
1. **Missing Properties/Methods**: TCPClient.LocalPortNumberOfClient, UDPServer properties, etc.
2. **Missing Types**: ProgramStatusEventHandler, SocketException, IPAddress
3. **Method Signature Mismatches**: SendDataAsync/ReceiveDataAsync parameter counts
4. **Enum Values**: eProgramStatusEventType.Stopping, ETHERNET_PARAMETER_TO_GET constants
5. **Constructor Overloads**: TCPServer 2-parameter constructor, CrestronQueue constructor

### 📁 File Status
#### ✅ Complete/Stable:
- `WebAndNetworking.cs` - HTTP/HTTPS clients with proper namespace separation
- `Extensions.cs` - CrestronInvoke and CrestronEthernetHelper (cleaned of duplicates)
- `Console.cs` - ErrorLog, CrestronDataStoreStatic basics
- `CrestronLogger.cs` - Proper namespace structure

#### 🔄 In Progress:
- `TCPClient.cs` - Added most properties/methods, needs final validation
- `TCPServer.cs` - Missing _bufferSize field, needs event handlers
- `UDPServer.cs` - Missing properties and method overloads
- `SystemTypes.cs` - Needs InitialParametersClass and CrestronEnvironment extensions

### 🧪 Test Strategy
- **Transparent Mocking**: No modifications to PepperDash.Core source files required
- **Test Configuration**: Uses CrestronMock project references instead of real Crestron libraries
- **API Compatibility**: Mock implementations maintain identical public API surface

### 🔄 Command to Continue
```bash
cd /Users/awelker/source/pepperdash/Essentials
dotnet build src/PepperDash.Core/PepperDash.Core.csproj -c Test --verbosity minimal
```

### 📝 Notes
- User has been manually editing files, so always check current file contents before making changes
- Focus on Test configuration only - don't modify Debug/Release builds
- All namespace migration work is complete and should be preserved
- HTTP/HTTPS mocking architecture is solid and working well

### 🎯 Success Criteria
Goal: Clean build of PepperDash.Core with Test configuration, enabling .NET 8 unit testing with transparent Crestron API mocking.
