Overview

In this course, the first step is to explore how to extend the user experience in model-driven apps. Users interact with the platform primarily through apps, and customizing this interaction can improve usability and efficiency. By leveraging JavaScript and TypeScript, you can trigger custom behaviors when a user opens an app, clicks a button, or interacts with form components.

Creating code components allows you to replace or enhance standard elements in a model-driven app. For example, you could design a custom visual component for displaying data in a new layout, or automate user interface interactions that would otherwise require manual input. Visual Studio Code provides a lightweight, powerful environment to write and debug these scripts.

Developing Plug-ins

Next, you will learn to create plug-ins using C#. Plug-ins allow you to attach code to specific platform events in Dataverse. When a record is created, updated, or deleted, your plug-in can automatically perform additional actions such as data validation, calculation, or integration with external systems.

This course will guide you through the process of registering plug-ins, handling platform messages, and creating robust event-driven logic. You will also explore how to define custom messages that extend the default capabilities of the platform.

Creating Custom Connectors

Custom connectors allow the Power Platform to interact with external services and APIs. In this course, you will learn to develop connectors using Azure Functions and integrate them seamlessly into your apps. This enables automation, data synchronization, and connectivity with third-party services.

You will also explore how to register external endpoints and ensure secure, efficient communication between systems. By creating custom connectors, you can reduce manual intervention, streamline business processes, and extend the overall capabilities of your solutions.

Integrating Data and Workflows

Data integration is a key component of extending the Power Platform. You will learn how to publish and consume Dataverse events, synchronize data across systems, and implement workflows that ensure accurate and timely processing of business information.

By combining plug-ins, custom connectors, and Power Automate flows, you can create end-to-end solutions that integrate multiple systems, maintain data integrity, and automate complex business processes.

Designing Technical Solutions and ALM

A strong understanding of technical architecture is essential for building scalable and maintainable solutions. In this course, you will learn how to validate requirements, plan solution design, and implement Application Lifecycle Management (ALM) best practices.

ALM ensures that solutions are deployed, updated, and maintained efficiently. You will learn strategies for source control, versioning, deployment, and error handling to ensure that your solutions are robust and production-ready.

Tools and Environment Setup

The course guides setting up essential tools for development. You will learn to install Visual Studio, Visual Studio Code, and other tools required for coding, debugging, and deploying solutions. You will also see how to create a free Power Platform trial environment for hands-on practice.
