## Description

This layer adds experimental support for C# language using [OmniSharp][].

## Packages Included

- [OmniSharp-emacs][]
- [OmniSharp-server][]

## Install

To use this contribution add it to your `~/.spacemacs`

```elisp
(setq-default dotspacemacs-configuration-layers '(csharp))
```

### Prerequisites

#### ASP.NET 5

Follow the instructions for your platform [here][aspnet].

#### curl

You'll need [curl][] to be able to use the Omnisharp package. Use your favorite
package manager to install it (on Windows you can use [chocolatey][]).

Be sure to make the `curl` binary available to your PATH environment variable,
or set the variable `omnisharp--curl-executable-path` in your dotfile function
`dotspacemacs-config`:

```elisp
(setq-default omnisharp--curl-executable-path "/PATH/TO/CURL/curl")
```

#### Omnisharp server

You have to compile the OmniSharp server following the instructions which can
be found [here][server_install].

Don't forget to add the server binary directory to your system PATH environment
variable. The full path the binary can also be directly referenced in the
variable `omnisharp-server-executable-path` (put this in your
`dotspacemacs-config` function):

```elisp
(setq-default omnisharp-server-executable-path "/PATH/TO/OMNISHARP/OmniSharpServer")
```

OmniSharp should now automatically load and start a server when you open a
`.cs` file.

## Caveats

- It's currently not possible to create a C# solution outside of an IDE such as
[MonoDevelop][], it's therefore recommended that you install it to create your
solutions.

- Debugging is possible using [SDB][].
