Debug an extension

Building and debugging a WindowSill extension is a straightforward process. This guide will walk you through the necessary steps.

Build & Run

First, open the project your created in the previous page in your favorite IDE or text editor (Visual Studio, Visual Studio Code or JetBrains Rider).

Then, you should simply be able to press F5 to start the debugger. Your project will build, then WindowSill will start (or restart if it was already running), and your extension will be loaded. The MyExtension sill will appear as soon as you start Notepad on your machine and give it the focus.

In the next section, we will dive more into how this works and how to create your own sill.
