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 |
||||||
|
``` |
||||||
|
|
||||||
|
