Legacy .NET 1.1–2.x and VB6 Application Maintenance

The contract involves the sustained maintenance and support of legacy mission-critical applications built on outdated technologies, specifically the .NET Framework versions 1.1 through 2.x and Visual Basic 6. The scope includes essential activities such as ongoing bug fixes, security and operational patching, and ensuring system availability to maintain uninterrupted functionality in a production environment. These applications are deemed vital to the operations of Export Development Canada, requiring specialized expertise to manage systems that are no longer supported by standard vendor updates or modern development frameworks. The contract is structured as a subcontract under NAICS code 541511, which corresponds to custom computer programming services, and is tied to the Government of Canada through Export Development Canada. It is solicited for performance within the National Capital Region, with a posted date of June 30, 2026, and a response deadline of July 13, 2026. The absence of set-aside provisions indicates no specific vendor classification requirements, and bidders must demonstrate proven experience with obsolete .NET and VB6 environments to meet the stringent reliability and continuity demands of the supporting government mission.
