+
+The Greeter demo illustrates how to send a request and wait for the response.
+
+You can build the client and server applications with:
+
+``` shell
+dotnet build
+```
+
+First start the Server program:
+
+```shell
+cd Server
+dotnet run
+```
+
+In a separate terminal, start the Client program:
+
+```shell
+cd Client
+dotnet run
+```
