+# .NET 10 and C# 12 Upgrade Notes
+
+## Completed Upgrades
+
+### Main Repository Projects
+
+All projects in the main repository have been successfully upgraded to .NET 10 and C# 12:
+
+- **WinPrint.Core**: netcoreapp3.1 → net10.0-windows, C# 8.0 → C# 12
+- **WinPrint.LiteHtml**: netcoreapp3.1 → net10.0-windows
+- **WinPrint.Console**: netcoreapp3.1 → net10.0-windows
+- **WinPrint.WinForms**: netcoreapp3.1 → net10.0-windows
+- **WinPrint.Core.UnitTests**: netcoreapp3.1 → net10.0-windows
+
+### Package Updates
+
+Major package updates include:
+- System.Linq.Dynamic.Core: 1.1.0 → 1.7.1 (fixes CVE vulnerability)
+- PowerShell SDK: 7.0.0 → 7.4.0
+- Serilog: 2.9.1 → 4.0.0
+- xUnit: 2.4.1 → 2.7.0
+- Microsoft.NET.Test.Sdk: 16.6.1 → 17.9.0
+- System.Drawing.Common: 4.7.0 → 8.0.0
+
+### Build System
+
+- GitHub Actions workflow updated to use .NET 10.0.x
+- PostBuild events made cross-platform compatible with OS conditionals
+
+## Submodule Updates Required
+
+The following submodules need to be updated in their respective repositories:
+
+### 1. libvt100 (https://github.com/tig/libvt100.git)
+
+**File**: `src/libvt100.csproj`
+
+Changes made:
+- SDK: Microsoft.NET.Sdk.WindowsDesktop → Microsoft.NET.Sdk
+- TargetFrameworks: netcoreapp3.1 → net10.0;net10.0-windows (multi-target)
+- LangVersion: 8.0 → 12
+- Added: EnableWindowsTargeting = true
+- System.Drawing.Common: 4.7.0 → 8.0.0
+- Added conditional UseWindowsForms for net10.0-windows target
+
+**Reason**: The library needed multi-targeting to support both Windows and non-Windows builds. The net10.0 target allows the library to be referenced by cross-platform projects, while net10.0-windows provides Windows Forms support.
+
+### 2. PowershellAsync (https://github.com/tig/PowershellAsync.git)
+
+**File**: `PowerShellAsync/PowerShellAsync.csproj`
+
+Changes made:
+- TargetFramework: netcoreapp3.1 → net10.0
+- System.Management.Automation: 7.0.0 → 7.4.0
+
+**Reason**: Updated to support .NET 10 and latest PowerShell SDK.
+
+## Next Steps
+
+1. **For submodule owners**: The changes made to libvt100 and PowershellAsync should be committed to their respective repositories
+2. **After submodule updates**: Update the submodule references in this repository to point to the new commits
+3. **Testing**: Run full integration tests on Windows to ensure all functionality works correctly
+4. **Optional**: Consider updating the installer project (currently uses .NET Framework 4.7.2)
+
+## Verification
+
+✅ All projects build successfully on Linux (CI environment)
+✅ All unit tests pass
+✅ Cross-platform build compatibility verified
+✅ Security vulnerability in System.Linq.Dynamic.Core resolved
