GridGain for .NET/C#

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

.NET Core 2.0+, .NET Framework 4.0+

Running a Simple .NET Example

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
> dotnet add package GridGain
This modifies the project file - .csproj - to add dependencies.

Open Program.cs in any text editor and replace the contents as follows:

using System;
using Apache.Ignite.Core;

namespace GridGain.GettingStarted
{
    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));
        }
    }
}

using System;
using Apache.Ignite.Core;
using GridGain.Core;

namespace GridGain.GettingStarted
{
    class Program
    {
        static void Main()
        {
            var cfg = new IgniteConfiguration
            {
                PluginConfigurations = new[]
                {
                    // Enable GridGain plugin.
                    new GridGainPluginConfiguration()
                }
            };

            IIgnite ignite = Ignition.Start(cfg);

            var cache = ignite.GetOrCreateCache<int, string>("my-cache");
            cache.Put(1, "Hello, World");
            Console.WriteLine(cache.Get(1));

            IGridGain gridGain = ignite.GetGridGain();
            Console.WriteLine(gridGain.GetProduct().GetLicense());
        }
    }
}

Save and then run the program:

> dotnet run

As a result, you should see a node launch and the "Hello, World" text displayed right after the launch.
