Which components are not recommended for the use of auto-resolve?

The choice indicating that Visualforce Pages and Apex Triggers are not recommended for the use of auto-resolve is particularly important to understand within the context of deployment and change management practices in Salesforce.

In Copado and other deployment tools, "auto-resolve" is a functionality that helps automate the resolution of conflicts during the deployment process when changes are made in parallel to the same components. However, certain components like Visualforce Pages and Apex Triggers are sensitive to changes and can lead to complex conflicts that are not easily resolvable through automation.

Visualforce Pages often include specific markup and logic that must align precisely with the application’s requirements, meaning that when several developers modify a single Visualforce Page concurrently, conflicts can arise that require manual intervention to address context and application behavior.

Apex Triggers also involve critical business logic that directly manipulates data upon certain conditions being met. Conflicts in these triggers can result in unexpected behaviors or data integrity issues if resolved incorrectly or automatically without human oversight.

Overall, the recommendation is that due to the nature of these components, they require careful consideration and manual intervention rather than relying on the automated conflict resolution provided by the auto-resolve feature, to ensure that applications continue to function correctly and as intended post-deployment.
