 ## Why use gRPC?
 
-Our example is a simple route mapping application that lets clients get information about features on their route, create a summary of their route, and exchange route information such as traffic updates with the server and other clients.

 ## Defining the service
 
-Our first step (as you'll know from [Getting started](..) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [`examples/protos/route_guide.proto`](../protos/route_guide.proto).

+Now let's look at our streaming methods. If you've already read [Creating the
+server](#server) some of this may look very familiar - streaming RPCs are
+implemented in a similar way on both sides. Here's where we call the server-side
+streaming method `ListFeatures`, which returns a stream of geographical
+`Feature`s:
 
 ```cpp
-    std::unique_ptr<ClientReader<Feature> > reader(
-        stub_->ListFeatures(&context, rect));
-    while (reader->Read(&feature)) {
-      std::cout << "Found feature called "
-                << feature.name() << " at "
-                << feature.location().latitude()/kCoordFactor_ << ", "
-                << feature.location().longitude()/kCoordFactor_ << std::endl;
-    }
-    Status status = reader->Finish();
+std::unique_ptr<ClientReader<Feature> > reader(
+    stub_->ListFeatures(&context, rect));
+while (reader->Read(&feature)) {
+  std::cout << "Found feature called "
+            << feature.name() << " at "
+            << feature.location().latitude()/kCoordFactor_ << ", "
+            << feature.location().longitude()/kCoordFactor_ << std::endl;
+}
+Status status = reader->Finish();
 ```
 
-Instead of passing the method a context, request, and response, we pass it a context and request and get a `ClientReader` object back. The client can use the `ClientReader` to read the server's responses. We use the `ClientReader`s `Read()` method to repeatedly read in the server's responses to a response protocol buffer object (in this case a `Feature`) until there are no more messages: the client needs to check the return value of `Read()` after each call. If `true`, the stream is still good and it can continue reading; if `false` the message stream has ended. Finally, we call `Finish()` on the stream to complete the call and get our RPC status.

Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.

+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
+  ```

+The nuget add-in available for Xamarin Studio and Monodevelop IDEs is too old to

+
+Using these IDEs, a workaround is as follows:
+* Obtain a nuget executable for your platform and update it with
+ `nuget update -self`. 
+* Navigate to this directory and run `nuget restore`.
+* Now that packages have been restored into their proper package folder, build the solution from your IDE.
