Testing the Waters: Why Power Apps Preview Isn’t Always Ready for Prime Time

Preview features are early releases provided to allow developers and organizations to explore and test new capabilities before they are fully supported. These features may change, have limited documentation, and are not recommended for production environments. In contrast, GA features are stable, fully supported by Microsoft, and ready for use in live environments.


Key Points About Preview Mode

1. Early Access Feature

Microsoft releases features in Preview to allow developers and organizations to try them before general availability (GA).

2. Not Fully Supported for Production

  • Preview features may have bugs, performance issues, or missing functionality.
  • Microsoft does not guarantee full support if these features cause issues in production apps.

3. Subject to Change

  • Features in preview can change significantly before general release.
  • Certain properties, behaviors, or APIs may be updated or removed.

4. Feedback Opportunity

  • Microsoft collects feedback from early users to improve the feature before GA.
  • Using preview features in non-production environments is recommended for testing.

5. Common in Power Apps

  • Examples include Modern Controls, Virtual Tables, or Co-Pilot integrations before GA.
  • In your case, the modern dropdown is still in preview mode, which is why it may not behave consistently inside a gallery.

Best Practice for Developers and Architects

  • Use Preview Features only in Dev/Test environments.
  • Avoid in production apps until they are GA (Generally Available).
  • Always monitor release notes to track updates or changes to preview features.

Effective Strategies for Debugging Plugins in Dynamics CRM

Image
In a recent interview, I was asked about debugging plugins in Dynamics CRM. The interviewer specifically wanted to know my approach to plugin debugging. In response, I mentioned using the Plugin Registration Tool profiler. However, I later realized there are multiple methods to debug plugins in Dynamics CRM/Dataverse, each essential for efficient troubleshooting. Debugging plays a crucial role in development, and having a solid understanding of various debugging approaches can help streamline issue resolution in Dynamics 365. Here, I'll explore different techniques for debugging plugin code. There are below options to use in the plugin in Dynamics CRM/Dataverse ITracingService : In Dynamics CRM plugin development, ITracingService is a service provided within the plugin's execution context that logs information for tracing and debugging. It allows developers to capture real-time. Plugin Profiler : A plugin profiler in Dynamics CRM (or Dataverse) is a debugging tool in the Plugi...

Exploring the Differences: Managed vs. Unmanaged Solutions in Dynamics CRM/Dataverse

Image
In Dynamics CRM/Dataverse, solutions are central to Application Lifecycle Management (ALM) , providing a structured way to manage, package, and distribute customizations across environments. Microsoft uses solutions to transfer apps and customizations by exporting them from one Dataverse environment and importing them into another.  Each solution is authored and maintained by a publisher and includes components like Power Apps (canvas and model-driven), flows, entities, forms, connectors, web resources, and configurations—excluding business data. Solutions streamline ALM practices within Microsoft Power Platform. In Dynamics CRM/Dataverse, there are two types of solutions: Managed and Unmanaged . When planning an implementation, it’s important to understand the advantages and disadvantages of each to make an informed decision. Let’s explore both types to determine the best approach for development and deployment. In Dynamics 365 CRM, a managed solution is a fully packaged solution ...

Connecting the Dots: FetchXML and Web API Integration in Dataverse

Image
 In Dataverse, FetchXML and the Web API are two powerful mechanisms for retrieving data and interacting with entities. Here's a brief overview of each and how they can be integrated: 1.    FetchXML :      -   Definition:   FetchXML is a proprietary query language used in Microsoft Dynamics 365 and Dataverse for querying data from entities.    -   Usage:   FetchXML queries can be used to retrieve data based on complex criteria, perform aggregations, and filter records.    -   Features:   FetchXML supports various query expressions, including conditions, sorting, grouping, and aggregation functions.    -   Integration:   FetchXML queries can be executed programmatically using client-side scripting, server-side code, or through tools like the Dynamics 365 Web API. 2.    Web API :      -   Definition:  ...
