This is a simple tutorial about python and C# using the Dynamic Language Runtime with IronPython.

I use Visual Studio 2019 and .NET Framework 4.7.2 with my Console C# project named DynamicLanguageRuntime_001.

Let's install the package with Visual Studio by open the console using the main menu: Tools - NuGet Package Manager - Package Manager Console command.

PM> Install-Package DynamicLanguageRuntime
Package 'DynamicLanguageRuntime.1.2.3' already exists in project 'DynamicLanguageRuntime_001'
Time Elapsed: 00:00:01.2208674

Use Solution Explorer use right-click on References item from your project and use Add Reference ...

Into the new window dialog named Reference Manager on the Assemblies - Framework uses the edit box to search IronPython.

Then use the checkbox to select these two options: IronPython and IronPython.Modules.

See the screenshot from Visual Studio I.D.E.:

This is the source code I used:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using IronPython.Hosting;
using IronPython.Runtime;
using IronPython;
using Microsoft.Scripting.Hosting;
using Microsoft.Scripting;

namespace DynamicLanguageRuntime_001
{
    class Program
    {
        static void Main(string[] args)
        {
            // create python engine 
            ScriptEngine engine = Python.CreateEngine();
            // get and add paths to enfine
            var python_search_paths = engine.GetSearchPaths();
            python_search_paths.Add(@"C:\Program Files\IronPython 2.7\Lib");
            engine.SetSearchPaths(python_search_paths);
            // create a scope 
            ScriptScope scope = engine.CreateScope();
            // using CreateScriptSourceFromString
            engine.CreateScriptSourceFromString("print '... simple example with ironpython and C#'").Execute();
            // using Execute
            engine.Execute("print '                             by catafest!'", scope);
            // using ExecuteFile
            engine.ExecuteFile(@"D:\Projects\Python\testing\test_webpage_001.py", scope);
            dynamic testFunction = scope.GetVariable("GetFriends");
            var result = testFunction();
        }
    }
}
