C# Rapid Open Widgets
**C.R.O.W.** is a [widget toolkit](https://en.wikipedia.org/wiki/Widget_toolkit) and
rendering engine entirely developed in **C#**, offering a nice trade-off between
complexity of language and performances. Crow provides a declarative interface language
with styling and templates
called [IML](interface-markup-language) for **Interface Markup Language** similar to
[XAML](https://en.wikipedia.org/wiki/Extensible_Application_Markup_Language) and a binding system
for easy c# code linking.
You can visit the [Wiki](https://github.com/jpbruyere/Crow/wiki) or the [Project Site](https://jpbruyere.github.io/Crow/)
for documentation and tutorials.

## Getting Start
### Requirements
- [mono > 4.5](http://www.mono-project.com/)
- [Cairo Graphic Library](https://cairographics.org/) >= 1.10
- [rsvg library](https://developer.gnome.org/rsvg/) for svg rendering
- [nuget](https://www.nuget.org/).
### Building from source
_[Git](https://git-scm.com) has to be installed._
```bash
git clone https://github.com/jpbruyere/Crow.git # Download source code from github
cd Crow # Enter the source directory
nuget restore Crow.sln # Restore nuget packages
xbuild /p:Configuration=Release Crow.sln # Build with Mono
```
### Using nuget
* add [Crow.OpenTK NuGet package](https://www.nuget.org/packages/Crow.OpenTK/) to your project.
* Derive **CrowWindow** class.
* Load some widget in the **OnLoad** override with `CrowWindow.Load` .
* Build your project with **mono**. (**xbuild**)
- copy **Crow.dll.config** to output directory if you have trouble finding native libs.
