Answer
Razor parses .cshtml ? generates C# ? compiles to assembly ? caches output. Precompilation improves startup, reduces CPU usage, and enhances performance.
Quick Answer
In production, Razor views are precompiled to C# during dotnet publish — shipped as DLLs, no .cshtml files needed. View compilation uses Roslyn. With Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation in development, Razor recompiles views on change without app restart. The RazorPage base class and generated Execute() method render HTML by writing to a TextWriter.
