Custom .NET Applications

We build enterprise web apps on .NET 10, and move existing .NET applications onto it now that .NET 8 and .NET 9 support has ended.

.NET 8 AND .NET 9 SUPPORT ENDED ON 10 NOVEMBER 2026

Business-critical .NET apps, from an engineering team that also handles SAP and hardware

Since 10 November 2026, Microsoft no longer ships security fixes for .NET 8 and .NET 9. .NET 10 is the current long-term support release, supported until November 2028. We upgrade existing applications to it and build new ones on it: portals, approval workflows, quality systems, MIS dashboards and apps that talk to SAP, banks and shop-floor equipment.

The problems we are usually called in for

Apps losing security support

Applications on .NET 8 and .NET 9 no longer receive security fixes, and older .NET Framework versions are already out of support. IT security teams and auditors flag them, and the risk grows every month.

Processes stuck in Excel and email

Approvals, test records, schedules and reports live in spreadsheets, because no packaged product fits the way the business actually works.

Apps that do not connect

Custom apps that cannot post to SAP, read a weighbridge or a sensor, or alert staff on WhatsApp, so people re-key the same data every day.

Two ways we help

.NET MODERNIZATION
