WHY UPGRADE TO .NET 6+

.NET Framework Is In Maintenance Mode

Microsoft is no longer adding new features to .NET Framework. Modern .NET (6/7/8) is the future with significant performance improvements, cross-platform support, and continuous innovation.

Massive Performance Gains

.NET 6/7/8 delivers up to 40% better performance than .NET Framework through improved JIT compilation, better garbage collection, and optimized libraries.

FAQ

Common Questions

The .NET Framework is in maintenance mode with no new features. .NET 6/7/8 offers significant performance improvements (up to 40% faster), cross-platform support, better cloud integration, container support, and access to modern C# features. Migration ensures long-term support and access to the latest innovations.

While VB.NET is supported in .NET 6+, we often recommend C# conversion because: it has better tooling and IDE support, more developers available, more community resources and examples, and some newer .NET features are C#-first. However, if your team is comfortable with VB.NET, staying with it is perfectly valid.

Timeline depends on application size and complexity. A small application might take 1-2 months, while enterprise applications can take 6-12 months. We provide detailed estimates after assessment. Using incremental migration, you can start seeing benefits within weeks while the full migration continues.

Yes, Windows Forms is fully supported in .NET 6+. We can migrate your WinForms application to the latest .NET while preserving the UI. Alternatively, we can modernize to Blazor Desktop, MAUI, or web-based interfaces depending on your requirements.

WPF is fully supported in .NET 6+ and migrates well. We update your WPF application to modern .NET, resolve breaking changes, update deprecated APIs, and optimize performance. The UI remains unchanged unless you want modernization.

We migrate from Entity Framework 6 to Entity Framework Core, which offers better performance and new features. This includes updating your data models, DbContext, migrations, and queries. We ensure all database operations work correctly after migration.

ASP.NET Web Forms is not supported in .NET Core/.NET 6+. We migrate Web Forms applications to ASP.NET Core with Razor Pages, Blazor, or a modern SPA framework (React/Angular). While this requires UI changes, we preserve all business logic and functionality.

Yes, we handle third-party control migration. Many vendors (Telerik, DevExpress, Syncfusion) offer .NET Core versions of their controls. Where direct equivalents don't exist, we find alternatives or implement custom solutions that match the original functionality.

We analyze all COM dependencies and either find .NET alternatives, wrap them for compatibility, or use .NET's COM interop capabilities. For Windows-specific features, we ensure the application runs on Windows while still benefiting from modern .NET performance.

Yes, we offer comprehensive post-migration support including bug fixes, performance optimization, security updates, and feature enhancements. We also provide training for your team on the new .NET platform and best practices.
