-In Solution Explorer, there are several file properties that you can interact with by using the right-click context menu. For more information about the right-click context menu options, see the [Manage project and solution properties](managing-project-and-solution-properties.md) page.

+
+What you see in the context menu from the **Solution** node also depends on your solution. The following screenshot highlights the following extra options: **Project Dependencies**, **Project Build Order**, **Set Startup Projects**, and a **Git** fly-out menu. These extra options appear when you add another project to the solution and then add the solution to a repo.

+## Add menu
+
+In the Solution Explorer context menu, one of the most useful options is the **Add** fly-out menu. From it, you can [add another project](../get-started/csharp/tutorial-console-part-2.md#add-another-project) to a solution. You can also [add an item](reference/add-new-item-command.md) to a project, and more.

+:::image type="content" source="media/solution-explorer-context-menu-add-flyout.png" alt-text="Screenshot of the Add fly-out menu from the right-click context menu in Solution Explorer.":::
+
+You can view the **Add** fly-out menu from either the **Solution** node, the **Project** node, or the **Dependencies** node. The options vary, depending on which node you use.

+For a tutorial that walks you through how to add items and projects by using the context menu in Solution Explorer, see the [Introduction to projects and solutions](../get-started/tutorial-projects-solutions.md#add-an-item-to-the-project) page.
