# Singularity
[](https://discord.gg/cKFnjjk) [](https://www.nuget.org/packages/Singularity/) [](https://dev.azure.com/Barsonax/Singularity/_build/latest?definitionId=7&branchName=master)  [](https://sonarcloud.io/dashboard?id=Barsonax_Singularity) [](https://sonarcloud.io/dashboard?id=Barsonax_Singularity) [](https://sonarcloud.io/dashboard?id=Barsonax_Singularity)  [](https://beerpay.io/Barsonax/Singularity)
## Features
- Extreme performance, Singularity is one of the fastest if not the fastest dependency injection container out there. Don't believe me? Check out my [benchmarks](#Benchmarks) or if you want a second opinion check out the benchmarks that Daniel Palme made [here](https://github.com/danielpalme/IocPerformance).
- Clean fluent API.
- [Source Link](https://github.com/dotnet/sourcelink) enabled
- Generic wrappers:
1. `Func`
1. `Lazy`
1. `Expression>`
1. And any other generic wrapper you may have defined yourself.
- Collection support:
1. `IEnumerable`
1. `IReadOnlyCollection`
1. `IReadOnlyList`
1. `T[]`
1. `List`
1. `ICollection`
1. `IList`
1. `HashSet`
1. `ISet`
- Supports open generics.
- Supports resolving unregistered concrete types.
- Supports decorators.
- Supports method and property injection without forcing you to litter attributes all over your code base. All configuration is kept inside the container.
- Supports dynamically picking the most suitable constructor based on the available types that can be resolved.
- Auto dispose, this is off by default but can be turned on with `With(DisposeBehavior)`or adding the lifetimes you want to auto dispose to `SingularitySettings.AutoDisposeLifetimes`.
- Custom finalizers with the `WithFinalizer(Action)` method.
- Supports Transient, Singleton and Scope lifetimes.
- Supports child containers.
- Supports best fit constructor selection
- Clear error messages and fail fast to point you in the right direction as fast as possible.
## Getting started
### Installation
`Singularity` can be installed through nuget. The packages that are available can be found in the [nuget](#nuget) section
### A simple example
Its easy to setup a container and request a instance:
```cs
var container = new Container(builder =>
{
builder.Register();
});
var instance = container.GetInstance();
```
However `Singularity` can do much more than this simple example. You can request the instance with different wrapper types such as `Lazy`:
```cs
var lazyInstance = container.GetInstance>();
```
Or you can request the factory to create the instance:
```cs
var factory = container.GetInstance>();
```
You can even request the expression itself:
```cs
var instanceExpression = container.GetInstance>>();
```
Ofcourse its possible to combine these with for instance a collection type such as IEnumerable or IReadOnlyList:
```cs
var instanceExpressions = container.GetInstance>>>(); //Returns all expressions for IPlugin registrations
```
Advanced scenarios such as open generics are also supported.
