gRPC in 3 minutes (C#)
========================
BACKGROUND
-------------
This is a different version of the helloworld example, using the dotnet sdk
tools to build and run.
For this sample, we've already generated the server and client stubs from [helloworld.proto][].
Example projects in this directory depend on the [Grpc](https://www.nuget.org/packages/Grpc/)
and [Google.Protobuf](https://www.nuget.org/packages/Google.Protobuf/) NuGet packages
which have been already added to the project for you.
The examples in this directory target .NET 4.5 framework, as .NET Core support is
currently experimental.
PREREQUISITES
-------------
- The DotNetCore SDK cli.
- The .NET 4.5 framework.
Both are available to download at https://www.microsoft.com/net/download
BUILD
-------
From the `examples/csharp/helloworld-from-cli` directory:
- `dotnet restore`
- `dotnet build **/project.json` (this will automatically download NuGet dependencies)
Try it!
-------
- Run the server
```
> cd GreeterServer
> dotnet run
```
- Run the client
```
> cd GreeterClient
> dotnet run
```
Tutorial
--------
You can find a more detailed tutorial about Grpc in [gRPC Basics: C#][]
[helloworld.proto]:../../protos/helloworld.proto
