Your c# code to execute, the plugin will rebuild your code if detect some change. These are some examples of the target code for this plugin:

Simple example:

            //Simple Example
            public class JenkinsPlugin
            {
                public static void ScriptMain()
                {
                    Console.WriteLine("Hello World from c#!!!");
                }
            }

Saving environment variables:

            // Complete example
            using DotNetTools.Jenkins;
            using System;        

            public class JenkinsPlugin
            {
                public static void ScriptMain(JenkinsManager manager)
                {
                    Console.WriteLine("Hello World from c#!!!");
                    manager.SetSessionEnv("PI", Math.PI.ToString());
                }
            }

You can use this two methods from the DotNetTools.Jenkins.JenkinsManager class:

            public void SetSessionEnv(string key, string value);
            public string GetSessionEnv(string key);
