DESCRIPTION
The organization seeks a vendor to provide web-based modernization software and collaborate as a software development partner for ongoing modernization of its proprietary line-of-business applications. The primary objective is to upgrade existing .NET Framework/Windows Forms applications to .NET 10 with WinUI 3 (Windows App SDK) for the desktop user interface, while preserving the current SQL Server 2019 database structure and ensuring stored-procedure-based data access.
The selected vendor will be responsible for providing system and application architecture diagrams, designing application components and data access patterns that adhere to .NET industry best practices, and developing support for unit and integration testing where feasible. The modernization approach must be incremental, minimize risk, and ensure that the updated applications maintain complete functional parity with legacy systems. The upgrade should also support side-by-side deployment and allow for rollback to the original application if required.
