To prepare for deploying a software deployable package to a test environment, you can use two possible methods. First, in Azure DevOps, you can queue a build from the corresponding branch and upload the package to the asset library. This method involves creating a build pipeline in Azure DevOps that generates the deployable package and then uploads it to the Dynamics Lifecycle Services (LCS) project's asset library. Second, in Visual Studio, you can create a Dynamics 365 deployment package and upload the package to the asset library. This method involves using the Visual Studio tools to create the package and then manually uploading it to the LCS asset library. Both methods ensure that the deployable package is available in LCS for deployment to the test environment.
To create an extension class in Dynamics 365 Finance, you need to mark the class as final. This is because extension classes cannot be derived from, and marking them as final ensures that they remain final. Extension classes in Dynamics 365 are used to extend existing functionality and are adorned with the ExtensionOf attribute. The correct action to perform is to mark the class as final.
A model in Dynamics 365 Finance is a group or collection of elements that constitute a distributable software solution, making it a design-time concept. It includes metadata and source files and often represents customizations of an existing solution. A package is a deployment unit that can contain one or more models, allowing for the organization and deployment of these solutions. These three design concepts accurately explain the relationships between models, packages, and projects.
