+The ASP.NET Core Worker Service template provides a starting point for writing long running service apps. To use the template as a basis for a hosted services app:
+
+# [Visual Studio](#tab/visual-studio)
+
+1. Create a new project.
+1. Select **ASP.NET Core Web Application**. Select **Next**.
+1. Provide a project name in the **Project name** field or accept the default project name. Select **Create**.
+1. In the **Create a new ASP.NET Core Web Application** dialog, confirm that **.NET Core** and **ASP.NET Core 3.0** are selected.

+# [Visual Studio Code / .NET Core CLI](#tab/visual-studio-code+netcore-cli)
+
+Use the Worker Service (`worker`) template with the [dotnet new](/dotnet/core/tools/dotnet-new) command from a command shell. In the following example, a Worker Service app is created named `ContosoWorkerService`. A folder for the `ContosoWorkerService` app is created automatically when the command is executed.
