How can you create an IoT Central application?

Creating an IoT Central application is primarily achieved by using the Azure portal. The Azure portal provides a user-friendly web interface where developers can create, configure, and manage various Azure services, including IoT Central. This process involves selecting IoT Central from the available resources, setting up the necessary parameters for the application, and deploying it directly through the portal, which facilitates a streamlined approach to managing IoT deployments.

Options that suggest alternatives, such as visiting a support page or relying on a desktop application, do not reflect the proper method for creating an IoT Central application. The support page provides assistance and resources but does not facilitate the actual application creation process. Similarly, there is currently no dedicated desktop application for creating an IoT Central application, as the functionality is integrated within the Azure cloud platform accessed through a web browser. Thus, utilizing the Azure portal is the correct and practical approach for this task.
