Hi Dick,
So what you need to do, is start up XIDE, in the opening screen press "New" to create a new Project (application container) and open it ("Select").
Then, when the main IDE window opens, select from the main menu Project|Create New|New Application. You will see some templates, the simplest one is "Basic x# application" which is already a "hello world" app

. Select it, press OK and the app will be created, you can view the code by clicking in the "Start.prg" file in the "Project" window at the right. Then press the green arrow toolbar button (or just press F5), this will compile and run the app, which shows a simple console with a message.
For something a little more advanced, you can create another application, selecting the "Basic x# form application" template. This will create an app with a window, select the Form1.prg file item in the Project window, expand it and double click on the form item (should be named BasicForm). This will show you a form, where you can put controls (from the Toolbox window at the right) and edit its properties, using the "Properties" window. So for example go to the Properties window, the 2nd row should have a property named "Text". Change the value to the right to Hello World and run the app with F5 again.
That's to get you started and start experimenting with x# and .Net. Of course it needs time to get familiar with it, please don't hesitate to ask any questions. And last but not least, welcome to x# and to this forum!
