GridGain for .NET/C#

This chapter explains how to use .NET Core to build and run a simple Hello World example in .NET that starts a node, puts a value into the node and then gets the value.

Prerequisites

GridGain .NET was officially tested on:

JDK

Oracle JDK 8 and later, Open JDK 8 and later, IBM JDK 8 and later

Linux (any flavor), Mac OSX (10.6 and up), Windows (XP and up), Windows Server (2008 and up), Oracle Solaris

ISA

x86, x64, SPARC, PowerPC

Network

No restrictions (10G recommended)

and:

Name	Value
.NET Framework	.NET 4.0+, .NET Core 2.0+
IDE	Visual Studio 2010+, Rider, Visual Studio Code

Name

Value

.NET Framework

.NET 4.0+, .NET Core 2.0+

IDE

Visual Studio 2010+, Rider, Visual Studio Code

Running a Simple .NET Example

Install .NET Core SDK (version 2+): https://dotnet.microsoft.com/download
Use the CLI (unix shell, Windows CMD or PowerShell, etc.) to run the following two commands:

> dotnet new console

This creates an empty project, which includes a project file with metadata and a .cs file with code.

And:

> dotnet add package GridGain.Ignite

This modifies the project file - .csproj - to add dependencies.

Open Program.cs in any text editor and replace the contents with the following:

using System;
using Apache.Ignite.Core;

namespace ggqsg
{
    class Program
    {
        static void Main(string[] args)
        {
          var ignite = Ignition.Start();
          var cache = ignite.GetOrCreateCache<int, string>("my-cache");
          cache.Put(1, "Hello, World");
          Console.WriteLine(cache.Get(1));
        }
    }
}

Save and then run the program:

> dotnet run

And that’s it! You should see a node launch and then display "Hello, World".

Using GridGain Web Console

GridGain Web Console is an interactive configuration, management, and monitoring tool, built on top of Apache Ignite Web Console.

Go to https://console.gridgain.com and create an account.
Log in with your new account and go to the "Monitoring Dashboard" screen. Click the three horizontal lines at the top in order to expand the left-hand menu:
Click the "Download Agent" button as shown in the screenshot below:
Extract the web agent into a separate folder.
Navigate to the folder where you extracted the web agent files, and execute the ignite-web-agent.sh (or ignite-web-agent.bat) script.
Ensure that the agent can connect to both console.gridgain.com and your single node cluster started earlier. Look for messages similar to the following in the agent’s log:
Go back to the console.gridgain.com Monitoring Dashboard and refresh it. Confirm that the tool successfully displays metrics for your local single node cluster.
