ASP.NET is Microsoft's mature, high-performance framework for building web applications and APIs — and it remains one of the most widely used web development technologies across UK enterprise. From financial services portals and government digital services to e-commerce platforms and healthcare applications, ASP.NET powers the web layer of thousands of UK organisations. IT Job Board lists active ASP.NET developer vacancies connecting skilled developers with employers who build on the Microsoft technology stack.
An ASP.NET Developer builds and maintains web applications using Microsoft's ASP.NET framework and the C# programming language. Modern ASP.NET development predominantly uses ASP.NET Core — a cross-platform, high-performance successor to classic ASP.NET — enabling developers to build RESTful APIs, MVC web applications, Blazor server-side or WebAssembly applications, and microservices. Many ASP.NET roles also involve working with SQL Server, Entity Framework, and Azure cloud services within a broader Microsoft ecosystem.
Junior ASP.NET developers typically earn £28,000–£40,000. Mid-level developers with 3–5 years of commercial ASP.NET Core experience earn £42,000–£60,000. Senior ASP.NET developers and technical leads earn £60,000–£80,000, with roles in London's financial sector or at leading cloud-native companies sometimes exceeding £90,000. Contracting day rates for experienced ASP.NET developers range from £350 to £600+ per day.
ASP.NET Core's performance, cross-platform capabilities, and deep integration with Azure make it an enduringly practical choice for enterprise development. Microsoft's continued investment in the platform — through .NET 8 and the upcoming .NET 9 — ensures strong long-term prospects. The huge installed base of .NET applications in UK enterprise creates ongoing demand for both greenfield development and legacy modernisation. ASP.NET skills travel across sectors and transfer directly into high-demand .NET-adjacent roles such as Azure development, Dynamics 365 customisation, and Microsoft 365 automation.

A: ASP.NET is Microsoft's original web framework, running only on Windows and the full .NET Framework. ASP.NET Core is its modern, cross-platform, high-performance successor built on .NET Core (now just .NET). UK employers now overwhelmingly prefer ASP.NET Core skills, though many maintain legacy ASP.NET applications.
A: Junior developers earn £28,000–£40,000. Mid-level ASP.NET Core developers earn £42,000–£60,000. Senior developers and technical leads earn £60,000–£80,000+. Contracting rates range from £350–£600+ per day.
A: Azure knowledge is very commonly expected in ASP.NET roles in the UK, as most .NET applications are hosted on or migrating to Azure. Azure fundamentals (AZ-900) is useful for all developers; AZ-204 (Azure Developer Associate) is valued for mid-to-senior roles.
A: Blazor is growing in adoption as it allows C# developers to build interactive web UIs without JavaScript. However, most UK ASP.NET roles still expect some JavaScript or TypeScript alongside Blazor knowledge, particularly for full-stack roles where React or Angular is used on the frontend.
