What is a common method used to deploy package solutions in Dynamics 365?

Using the Microsoft Dynamics 365 Package Deployer is a standard and widely accepted method for deploying package solutions in Dynamics 365. This tool is specifically designed to facilitate the deployment process by automating various tasks associated with the installation of solutions. It allows for the efficient deployment of custom solutions and their dependencies, ensuring that they are set up correctly in the target environment.

The Package Deployer streamlines the process, reducing the risk of human error during deployment and providing a more consistent deployment experience across different environments. By leveraging this tool, developers and administrators can also handle complex installations that involve multiple components or custom configurations, making it a crucial asset in a developer's toolkit when working with Dynamics 365 solutions.

In contrast, other options may not serve the specific purpose of deploying package solutions directly. For instance, utilizing the Dynamics 365 web interface is more geared toward managing existing solutions rather than deploying new packages. Azure Functions and Windows Task Scheduler are versatile frameworks for executing tasks in the cloud and scheduling jobs, respectively, but they are not specifically tailored for Dynamics 365 package deployment. Thus, the Package Deployer stands out as the most appropriate and effective choice for this task.
