.NET Migration in Newcastle

Migrating Newcastle applications from .NET Framework to modern .NET, where the first task is finding what has no successor. Several Framework technologies were not carried forward — server-side WCF, Web Forms, remoting — so an application built on one of those is facing a redesign of that layer rather than a port of it.

Why this comes up

The problem

The migration was estimated as a port, and a third of the application is built on a technology that no longer exists.

What you get

What we deliver

  • Technologies without a direct successor identified before anything is estimated
  • Replacement approach chosen for each, since the alternatives differ substantially
  • Incremental migration behind a proxy where the application is too large to move at once
  • Dependencies assessed for modern .NET support, including transitive ones
  • Configuration and hosting reworked, as the models differ meaningfully
  • Behaviour captured as tests before the layers producing it are replaced

.NET Migration in Newcastle — common questions

What genuinely does not port?
Server-side WCF, Web Forms and remoting are the main ones. Clients and alternatives exist for some, and the honest position is that these represent a redesign of that layer — which is why finding them early matters more than any other assessment step.
Can a large application move incrementally?
Yes, by routing traffic through a proxy that sends migrated paths to the new application and everything else to the old one. Each release moves a section, both run together, and the migration proceeds without a single high-risk cutover.
How do we handle dependencies?
Audit them including transitively, because one unsupported package deep in the graph can block everything above it. Most widely used libraries have moved; the ones that have not are usually internal or long abandoned, and both need a decision.
Is it worth doing at all?
For an application under active development, generally yes — performance, hosting options and access to current tooling. For a stable system nobody is changing, the Framework remains supported and the migration may be effort spent for benefits nobody will use.
Do you work with businesses across Tyne and Wear?
Yes. We are based in Leicester, United Kingdom and work with clients throughout North East, including Newcastle and the surrounding Tyne and Wear area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Newcastle businesses do you usually work with?
Remote monitoring and data-heavy work from the energy sector sits alongside a steady flow of product builds from the local tech community. Beyond that we work across Digital & Tech, Offshore Energy, Healthcare, Higher Education and Retail.
Do you cover the areas around Newcastle?
Yes — we work throughout North East, including Leeds, York. Newcastle is an urban area of roughly 820,000+, and we take on work across the wider Tyne and Wear region rather than the city boundary alone.
