A solution dependency occurs when one solution, known as a child, relies on another solution (the parent) to function correctly. For instance, a child solution may require specific features or components provided by the parent. In an unmanaged solution, these dependencies are created and maintained manually, whereas in a managed solution, these dependencies are automatically managed.
To view the dependencies of a solution, navigate to the ‘Solution’ area in Power Apps and select ‘Show Dependencies’.
Kinds of Dependencies
There are two types of dependencies: Hidden dependencies and Direct dependencies.
Direct Dependencies:
These are dependencies on components in the solution that are directly linked to other components. For instance, if a canvas app uses a specific entity, a direct dependency is created.
Hidden Dependencies:
Hidden dependencies are indirect associations that are not visible to the developers and can cause issues if not handled properly.
Managing Dependencies in Microsoft Power Platform
1. Identification:
Understanding your solution dependencies is the first step in managing them. This can be done through the ‘Check Dependencies’ tool available in the Microsoft Power Platform admin center.
2. Resolution:
Resolve dependencies by either including the dependent component in the same solution or ensuring that the solution the component depends on is already in the target system before importing the solution.
Dependency Management Using Solution Layers
Solution layers provide another way to manage dependencies in Microsoft Power Platform. Layers represent the order in which solutions are applied to the system. The lower layers contain the system or managed solutions, while the topmost layers contain unmanaged customizations.
When you export a managed solution, the system checks the solution layers, creating a snapshot of the current layer. This snapshot records all dependencies and uses this information to ensure components are imported in the correct order.
Tips for Managing Solution Dependencies
Here are some tips to effectively manage solution dependencies:
- Avoid unnecessary dependencies: Keep solutions as independent as possible. This makes them easier to manage, troubleshoot, and version.
- Use base solutions: If you have several solutions that all use the same components, consider creating a base solution that includes these common components.
- Document dependencies: Keep track of all dependencies, both direct and hidden, in a dedicated document to ensure nothing is overlooked.
Conclusion
In conclusion, managing solution dependencies effectively is a crucial skill for any Microsoft Power Platform Developer. It involves understanding the different types of dependencies, identifying them within your solutions, and using best practices to ensure they’re resolved properly. By mastering these techniques, you can ensure your solutions are robust, maintainable, and easy to troubleshoot. Study this topic to prepare for the PL-400 Microsoft Power Platform Developer exam, and you’ll be well-equipped to handle any solution dependency issues that may arise in your professional development career.
Practice Test
True or False: When managing solution dependencies, it is possible to include a managed solution inside an unmanaged solution.
- True
- False
Answer: False
Explanation: Only an unmanaged solution can exist inside a managed solution, not vice versa.
What does the solution checker in the Power Platform allow you to do?
- A. Resolve solution dependencies
- B. Identify potential performance issues
- C. Check for any missing components
- D. All of the above
Answer: D. All of the above
Explanation: The solution checker identifies potential performance issues, incorrect configuration, and missing dependencies among other things.
True or False: When working with solutions, it’s a best practice to explicitly include all dependent components.
- True
- False
Answer: True
Explanation: It’s important to ensure all dependent components are included in your solution so your solution can work as expected when it’s imported into a target environment.
When dealing with managed solutions, which of the following is NOT true?
- A. They cannot be modified
- B. They can have multiple publishers
- C. They can be exported
- D. They are not affected when their dependent unmanaged solutions are deleted
Answer: B. They can have multiple publishers
Explanation: Each managed solution can only have one publisher.
True or False: We can include the Common Data Service default solution into a Managed Solution.
- True
- False
Answer: False
Explanation: The Common Data Service default solution cannot be included in a managed solution. You can only add your own custom solutions.
What is the primary tool to manage solution dependencies in the Power Platform?
- A. Solution explorer
- B. Configuration migration
- C. Solution component dependencies
- D. Web API
Answer: C. Solution component dependencies
Explanation: Solution component dependencies tool helps you understand component dependencies within a solution which helps in managing solutions overall.
True or False: If you delete a solution, all the components within that solution are also deleted.
- True
- False
Answer: False
Explanation: Deleting a solution only removes the solution wrapper. The components within the solution exist until they are deleted individually.
What are the two states of a component in a solution?
- A. Active and Inactive
- B. Managed and Unmanaged
- C. Live and Draft
- D. Created and Deleted
Answer: B. Managed and Unmanaged
Explanation: In Power Platform, components within a solution are either managed or unmanaged. This determines their editability and overall lifecycle.
True or False: When a managed solution is uninstalled, all of its components and data remain in the system.
- True
- False
Answer: False
Explanation: When a managed solution is uninstalled, all the components and data associated with it are removed from the system.
Can we export an unmanaged solution that contains a managed solution?
- A. Yes
- B. No
Answer: B. No
Explanation: Managed solutions cannot exist within an unmanaged solution. Therefore, we cannot export an unmanaged solution that contains a managed solution.
Interview Questions
What are solution dependencies in the context of Microsoft Power Platform?
Solution dependencies are relationships between components in a solution that require one component to function properly with another.
How can you view solution dependencies in Power Platform?
You can view solution dependencies by navigating to Settings > Customizations > Customize the System > Solutions, selecting the solution, and clicking on the Dependencies tab.
What are the different types of solution dependencies?
There are three types of solution dependencies: Required, Recommended, and Optional.
How do you manage solution dependencies in Power Platform?
You can manage solution dependencies by resolving any missing or broken dependencies before importing or exporting a solution.
What happens if there are unresolved dependencies in a solution?
If there are unresolved dependencies in a solution, the solution import may fail or some components may not function properly.
Can you remove dependencies between components in a solution?
No, you cannot remove dependencies between components in a solution. Dependencies must be resolved to ensure proper functionality.
What is the purpose of managing solution dependencies?
Managing solution dependencies helps ensure that all required components are present and functioning properly within a solution to avoid errors or issues.
What are some common strategies for resolving solution dependencies?
Common strategies for resolving solution dependencies include adding missing components, updating dependencies, or removing components that are no longer needed.
How can you identify dependencies between components in a solution?
You can identify dependencies between components in a solution by reviewing the Dependencies tab for each component in the solution.
Why is it important to review solution dependencies before importing or exporting a solution?
Reviewing solution dependencies before importing or exporting a solution helps avoid potential errors or issues related to missing or broken dependencies.
What are the consequences of ignoring solution dependencies?
Ignoring solution dependencies can lead to functionality issues, errors, or failures when trying to deploy or use the solution.

Best practices for managing solution dependencies include regularly reviewing dependencies, resolving any issues promptly, and testing solutions thoroughly after resolving dependencies.
How can you automate the management of solution dependencies in Power Platform?
You can automate the management of solution dependencies by using tools such as Power Automate to trigger dependency checks before importing or exporting solutions.
