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

.NET Framework

.NET 4.0+, .NET Core 2.0+

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".
