When .NET Is The Right Choice
Choose .NET when
- You run on Microsoft infrastructureWindows Server, SQL Server, Active Directory and Azure fit together with little glue.
- The product is a long-lived business systemStrong typing and first-party tooling make a large codebase easier to maintain.
- You want one language across layersC# covers APIs, background services, desktop and, with Blazor, the browser.
- The server must handle heavy trafficASP.NET Core copes well with high request volumes and runs in Linux containers.
Consider something else when
- Your team lives in another ecosystemIf your engineers and libraries are all JVM or Node.js, adding .NET splits your skills.
- The core of the work is data sciencePython has the wider set of modelling libraries.
- You are writing low-level system codeRust or C++ give finer control over memory and hardware.
- The site is mostly contentA CMS or static site generator is simpler to run.
