Changing from Microsoft.NET.Sdk.WindowsDesktop to Microsoft.NET.Sdk may cause build issues or loss of Windows-specific features. The WindowsDesktop SDK provides additional functionality for WPF and WinForms applications. Verify that all Windows-specific features still work correctly with the standard SDK, or consider keeping the WindowsDesktop SDK while using the net8.0-windows target framework.
