PREREQUISITES
--------------
- Prerequisites: .NET Framework 4.5+, Visual Studio 2013 with NuGet extension installed (VS2015 should work).
- Windows: .NET Framework 4.5+, Visual Studio 2013 or 2015.
- Linux: Mono 3.2.8+, MonoDevelop 5.9 with NuGet add-in installed.
- Mac OS X: [homebrew][], Xamarin Studio with NuGet add-in installed.
HOW TO USE
--------------
**Windows**
- Open Visual Studio and start a new project/solution.

That will also pull all the transitive dependencies (including the native libraries that
gRPC C# is internally using).
- Helloworld project example can be found in https://github.com/grpc/grpc/tree/master/examples/csharp.
**Linux (Debian)**
Usage: Linux (Mono)
--------------
- Add [Debian jessie-backports][] to your `sources.list` file. Example:
- Prerequisites: Mono 3.2.8+, MonoDevelop 5.9 with NuGet add-in installed.
- Install Linuxbrew and gRPC C Core using instructions in https://github.com/grpc/homebrew-grpc
- gRPC C# depends on native shared library libgrpc_csharp_ext.so (Unix flavor of grpc_csharp_ext.dll).
This library will be installed to `~/.linuxbrew/lib` by the previous step.
To make it visible to mono, you need to:
```sh
echo "deb http://http.debian.net/debian jessie-backports main" | \
sudo tee -a /etc/apt/sources.list
```
- (preferred approach) add `libgrpc_csharp_ext.so` to `/etc/ld.so.cache` by running:
- Install the gRPC Debian package
```sh
$ echo "$HOME/.linuxbrew/lib" | sudo tee /etc/ld.so.conf.d/zzz_brew_lib.conf
$ sudo ldconfig
```
```sh
sudo apt-get update
sudo apt-get install libgrpc0
```
- (adhoc approach) set `LD_LIBRARY_PATH` environment variable to point to directory containing `libgrpc_csharp_ext.so` :
- gRPC C# depends on native shared library `libgrpc_csharp_ext.so` (Unix flavor of grpc_csharp_ext.dll).
This library is not part of the base gRPC debian package and needs to be installed manually from
a `.deb` file. Download the debian package `libgrpc_csharp_ext` from corresponding gRPC release on GitHub
and install it using `dpkg` .
```sh
$ export LD_LIBRARY_PATH=$HOME/.linuxbrew/lib:${LD_LIBRARY_PATH}
```
- (if you are contributor) installing gRPC from sources using `sudo make install_grpc_csharp_ext` also works.
```sh
# choose version corresponding to libgrpc you've installed.
wget https://github.com/grpc/grpc/releases/download/release-0_11_0/libgrpc-csharp-ext0_0.11.0.0-1_amd64.deb
dpkg -i libgrpc-csharp-ext0_0.11.0.0-1_amd64.deb
```
- Open MonoDevelop and start a new project/solution.
- Add NuGet package `Grpc` as a dependency (Project -> Add NuGet packages).
- Helloworld project example can be found in https://github.com/grpc/grpc/tree/master/examples/csharp.
Usage: MacOS (Mono)
--------------
**Mac OS X**
- WARNING: As of now gRPC C# only works on 64bit version of Mono (because we don't compile
the native extension for C# in 32bit mode yet). That means your development experience
with Xamarin Studio on MacOS will not be great, as you won't be able to run your
code directly from Xamarin Studio (which requires 32bit version of Mono).
- Prerequisites: Xamarin Studio with NuGet add-in installed.
- Install Homebrew and gRPC C Core using instructions in https://github.com/grpc/homebrew-grpc
- Install 64-bit version of mono with command `brew install mono` (assumes you've already installed Homebrew).
