Key features

Pure.DI is not a framework or library, but a source code generator for creating object graphs. To make them accurate, the developer uses a set of intuitive hints from the Pure.DI API. During the compilation phase, Pure.DI determines the optimal graph structure, checks its correctness, and generates partial class code to create object graphs in the Pure DI paradigm using only basic language constructs. The resulting generated code is robust, works everywhere, throws no exceptions, does not depend on .NET library calls or .NET reflections, is efficient in terms of performance and memory consumption, and is subject to all optimizations. This code can be easily integrated into an application because it does not use unnecessary delegates, additional calls to any methods, type conversions, boxing/unboxing, etc.

• DI without any IoC/DI containers, frameworks, dependencies and hence no performance impact or side effects.

  Pure.DI is actually a .NET code generator. It uses basic language constructs to create simple code as well as if you were doing it yourself: de facto it's just a bunch of nested constructor calls. This code can be viewed, analyzed at any time, and debugged.

• A predictable and verified dependency graph is built and validated on the fly while writing code.

  All logic for analyzing the graph of objects, constructors and methods takes place at compile time. Pure.DI notifies the developer at compile time of missing or cyclic dependencies, cases when some dependencies are not suitable for injection, etc. The developer has no chance to get a program that will crash at runtime because of some exception related to incorrect object graph construction. All this magic happens at the same time as the code is written, so you have instant feedback between the fact that you have made changes to your code and the fact that your code is already tested and ready to use.

• Does not add any dependencies to other assemblies.

  When using pure DI, no dependencies are added to assemblies because only basic language constructs and nothing more are used.
