.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

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.
