Aspect Injector
========================
**Aspect Injector** is an attribute-based framework for creating and injecting aspects into your .net assemblies.
### Project Status
[](https://www.nuget.org/packages/AspectInjector)
[](https://www.nuget.org/packages/AspectInjector)
[](https://www.nuget.org/packages/AspectInjector)
[](https://github.com/pamidur/aspect-injector/commits/master)
### Download
```bash
> dotnet add package AspectInjector
```
### Features
- Compile-time injection - works with Blazor and AOT
- Injecting **Before**, **After** and **Around** (wrap) **Methods**, **Constructors**, **Properties** and **Events**
- Injecting **Interface implementations**
- Supports any project that can reference **netstandard2.0** libraries, see [here](https://docs.microsoft.com/en-us/dotnet/standard/net-standard)
- Debugging support
- Roslyn analyzers for your convenience (only c# currently)
- Can work DI/IoC frameworks [#166](https://github.com/pamidur/aspect-injector/discussions/166)
Check out [samples](samples) and [docs](docs)
### Requirements
- (_semi-optional_) **Nuget 5.0+** for _transient build_ feature. All modern versions of VS and dotnetsdk have it.
_(If you still use project.json for some reason - make sure you add AspectInjector to all projects in the solution)_
- (_optional_) For analyzers to work in VSCode, don't forget to enable ```"omnisharp.enableRoslynAnalyzers": true```
### Known Issues / Limitations
- Unsafe methods are not supported and are silently ignored.
### Simple advice
#### Create an aspect with simple advice:
```C#
[Aspect(Scope.Global)]
[Injection(typeof(LogCall))]
public class LogCall : Attribute
{
[Advice(Kind.Before)] // you can have also After (async-aware), and Around(Wrap/Instead) kinds
public void LogEnter([Argument(Source.Name)] string name)
{
Console.WriteLine($"Calling '{name}' method..."); //you can debug it
}
}
```
#### Use it:
```C#
[LogCall]
public void Calculate()
{
Console.WriteLine("Calculated");
}
Calculate();
```
#### Result:
```bash
$ dotnet run
Calling 'Calculate' method...
Calculated
```
### Simple mixin
#### Create an aspect with mixin:
```C#
public interface IInitializable
{
void Init();
}
[Aspect(Scope.PerInstance)]
[Injection(typeof(Initializable))]
[Mixin(typeof(IInitializable))]
public class Initializable : IInitializable, Attribute
{
public void Init()
{
Console.WriteLine("Initialized!");
}
}
```
#### Use it:
```C#
[Initializable]
public class Target
{
}
var target = new Target() as IInitializable;
target.Init();
```
#### Result:
```bash
$ dotnet run
Initialized!
```
