# C# Rules
## Rules
<div class="toc">
<h2>Rules</h2>
<ul>
<li><a href="#csharp_library">csharp_library</a></li>
<li><a href="#csharp_binary">csharp_binary</a></li>
<li><a href="#csharp_nunit_test">csharp_nunit_test</a></li>
</ul>
</div>
## Overview
This is a minimal viable set of C# bindings for building csharp code with
mono. It's still pretty rough but it works as a proof of concept that could
grow into something more. If windows support ever happens for Bazel then this
might become especially valuable.
## Setup
Add the following to your `WORKSPACE` file to add the external repositories:
```python
load("@bazel_tools//tools/build_defs/dotnet:csharp.bzl", "csharp_repositories")
csharp_repositories()
```
## Examples
### csharp_library
```python
csharp_library(
name = "MyLib",
srcs = ["MyLib.cs"],
deps = ["//my/dependency:SomeLib"],
)
```
### csharp_binary
```python
csharp_binary(
name = "MyApp",
main = "MyApp", # optional name of the main class.
srcs = ["MyApp.cs"],
deps = ["//my/dependency:MyLib"],
)
```
### csharp\_nunit\_test
```python
csharp_nunit_test(
name = "MyApp",
srcs = ["MyApp.cs"],
deps = ["//my/dependency:MyLib"],
)
```
## Things still missing:
- Handle .resx files correctly.
- .Net Modules
- Conditionally building documentation.
- Pulling Mono in through a mono.WORKSPACE file.
## Future nice to haves:
- Building csproj and sln files for VS and MonoDevelop.
- Nuget Packaging
- Windows .NET framwork support
<a name="csharp_library"></a>
## csharp_library
```python
csharp_library(name, srcs, deps, warn=4, csc)
```
Builds a C# .NET library and its corresponding documentation.
