The hourly rate ranges between £30 and £150 per hour, depending on developer seniority, agency profile, and project complexity. For project-based work, a simple .NET application usually starts around £20,000 to £50,000, a mid-complexity system often falls between £50,000 and £150,000, and a large or enterprise-grade platform can go beyond £250,000.
It takes 2 to 7 months to complete a .NET project, depending on the project scope, complexity, and requirements. A small MVP or simple application takes 2 to 3 months, and a mid-sized business project takes 3 to 5 months. Whereas a complex or enterprise-level .NET project can take up to 7 months or more, depending on team size, selected methodology, and project needs.
C# is the core language used to build applications on the .NET platform. It defines the application logic, handles data processing, and interacts with .NET libraries to develop web apps, APIs, desktop software, and cloud-based systems.
Yes, .NET can be used for cross-platform mobile app development through .NET MAUI. It allows developers to build native apps for Android and iOS from a single shared codebase in C# and XAML. Moreover, it also supports Windows and macOS apps.

.NET development is most beneficial for industries such as finance, healthcare, e-commerce, logistics, education, and enterprise software.
.NET improves performance through Just-In-Time (JIT) compilation, efficient memory management, and optimized runtime (CLR). It also supports asynchronous processing and caching, which helps applications run faster and handle more users efficiently.
We use Azure DevOps, GitHub Actions, and Jenkins for CI/CD pipelines and automation. We also use Docker and Kubernetes for deployment, scaling, and environment management.
Blazor is a modern, open-source .NET framework that lets you build interactive web UIs using C# instead of JavaScript. You can use it if your project relies on the .NET ecosystem and you want to share logic between frontend and backend.
The main difference is that .NET Framework is Windows-only, while .NET Core and .NET 5/6/8 are cross-platform and more performant.
