NikolayP/Pure.DI.Templatesv2.2.9

Pure.DI is a compile-time dependency injection (DI) code generator. Supports .NET starting with .NET Framework 2.0, released 2005-10-27, and all newer versions.

Usage Requirements

• .NET SDK 6.0.4+
  Required for compilation. Projects can target older frameworks (e.g., .NET Framework 2.0).
• C# 8+
  Only required for projects using the Pure.DI source generator. Other projects support any C# version.

Key Features

✔️ Zero Overhead

Pure.DI is a .NET code generator designed to produce clean, efficient dependency injection logic. By leveraging basic language constructs, it generates straightforward code indistinguishable from manual implementation—essentially composing objects through nested constructor invocations. Unlike traditional DI frameworks, Pure.DI avoids reflection and dynamic instantiation entirely, eliminating performance penalties associated with runtime overhead.

✔️ Compile-Time Validation

All analysis of object, constructor, and method graphs occurs at compile time. Pure.DI proactively detects and alerts developers to issues such as missing dependencies, cyclic references, or dependencies unsuitable for injection—ensuring these errors are resolved before execution. This approach guarantees that developers cannot produce a program vulnerable to runtime crashes caused by faulty dependency wiring. The validation process operates seamlessly alongside code development, creating an immediate feedback loop: as you modify your code, Pure.DI verifies its integrity in real time, effectively delivering tested, production-ready logic the moment changes are implemented.

✔️ Works everywhere

The pure dependency injection approach introduces no runtime dependencies and avoids .NET reflection , ensuring consistent execution across all supported platforms. This includes the Full .NET Framework 2.0+, .NET Core, .NET 5+, UWP/Xbox, .NET IoT, Unity, Xamarin, Native AOT, and beyond. By decoupling runtime constraints, it preserves predictable behavior regardless of the target environment.
