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.

Dear Client, I have worked with C# and .NET applications for over 8.5 years, the majority of my career. I have worked on both web backends as well as desktop applications, and have created multiple WinForms apps during this period. I also have experience conducting upgrades of projects and dependencies multiple times in multiple high stake projects, and am confident about my ability to help you achieve your goal. I plan to take a step-by-step approach to this problem: Step-1: Backup the entire project with source code, dependencies and all. Step-2: Upgrade the project to .NET 8 Step-3: Check for any dependencies that are not supported and replace them with their latest versions. Step-4: In case a dependency doesn't have a compatible version, find an alternative dependency. Step-5: Check for build errors, and fix any errors occurring one by one. Step-6: Create a solution for the project. Step-7: Do multiple test runs. Step-8: User Acceptance Testing through video conference. Step-9: Final handover after fixing any remaining issue. Hope these steps show that I am very much experienced in this process. Hoping to hear back from you as soon as possible and helping you out! Best Regards, George M. George

Upgrading multiple projects from legacy Frameworks to .NET 8 while ensuring a clean build in Visual Studio 2026 requires careful handling of SDK-style project conversion and deprecated APIs. I’d start by converting each project to SDK-style format, retargeting to .NET 8 step-by-step. I’d then identify and replace obsolete Windows Forms controls and update configuration files systematically, testing after each change to keep the app stable. NuGet dependencies would be reviewed and swapped if needed. Progress updates would include small deliverables: project conversion, API updates, package audits, and final testing. My approach keeps communication steady and the delivery predictable, with a detailed migration report included. What parts of the solution have custom or third-party controls that might need special attention? Cheers, Ryan

Hi, I’m Jathin, a Full Stack Developer with nearly 2 years of hands-on professional experience working on enterprise-grade applications. This would be my first freelancing opportunity, and I’m genuinely excited about it because it aligns exactly with the kind of work I’ve been doing consistently over the last two years. My experience revolves around modernizing and optimizing legacy .NET applications, including migrating projects from older .NET Framework versions to .NET Core / .NET 8, converting projects to SDK-style, resolving deprecated APIs, updating NuGet dependencies, and ensuring the application behaves identically after migration. I’ve worked extensively with Windows Forms, backend-heavy systems, and performance-critical codebases. My core tech stack includes C#, VB.NET, .NET Framework, .NET Core/.NET 8, Windows Forms, ASP.NET, MVC, REST & SOAP APIs, SQL Server, MongoDB, Dapper, Angular, HTML, CSS, JavaScript, Python, and AI/LLM-based automation. I also use Git, CI/CD pipelines, Azure DevOps, and modern debugging/monitoring practices. What sets me apart is how I leverage AI tools to deeply analyze legacy code, refactor faster, reduce risk, and validate functional parity—allowing me to deliver high-quality migrations quickly and confidently. If given this opportunity, I’ll bring full ownership, transparency, and commitment to delivering a clean, future-ready solution.
