Project description:
"I have a small VB.NET solution that still targets several legacy Framework versions (3.0, 3.5, 4.0 and 4.8). It contains a traditional Windows Forms UI and a couple of supporting class-library projects. I now need the whole codebase lifted to .NET 8 so I can take advantage of the new language and runtime features that Visual Studio 2026 unlocks.

Your task is to:
• Convert every project file to SDK-style, retargeting each one to .NET 8.
• Resolve any obsolete APIs, replace deprecated Windows Forms controls where needed, and map configuration changes ([login to view URL] → appsettings, etc.).
• Update or swap NuGet packages so the solution builds cleanly on the latest toolchain.
• Make sure the application behaves identically after the upgrade—forms load correctly, events fire, and all existing functionality remains intact.
• Deliver a single solution that opens and compiles without warnings in Visual Studio 2026, accompanied by a concise migration report (what changed, why, and any future recommendations).

Acceptance criteria: the migrated solution builds successfully on .NET 8, launches its Windows Forms UI with no runtime errors, and all previously working features operate as before.

Let me know your relevant upgrade experience and an estimated turnaround time so we can get started." (client-provided description)
