This course teaches the requirements for the Microsoft Certificate PL-400 "Power Platform Developer", and focuses on programming in JavaScript/TypeScript and C# to expand the Power Platform.

We'll start off by looking at extending the user experience. Using Visual Studio Code, we will create some JavaScript code that will run when our model-driven app is opened. We'll then create some command buttons, along code to run when the user clicks these. We will then concentrate on create code components, replacing existing parts of the model-driven app.

We'll then look at creating a plug-in. The code that we'll write in Visual Studio will be attached to messages created by Power Platform, allowing our code to run when Dataverse rows are created, updated or deleted. We'll also look at creating our own custom messages as well.

Next up is Custom Connectors. We will create an Azure Function, and find out when it can run. We will then integrate that Function into our Power Platform by creating a custom connector. We'll also register external endpoints, including in Azure, so that messages can be automatically sent to other apps, reducing the burden on the Power Platform.

We'll finish off by looking at creating a technical design, and any other requirements not covered in previous exams, such as advanced Power Automate flows and implementing Application Lifecycle Management (ALM).

No prior knowledge is required - we'll even see how to get a free Power Platform trial!

There are regular quizzes to help you remember the information, so you can be sure that you are learning.

Once you have completed this course, you will have a good knowledge of how to make extend Power Platform using JavaScript and C#. And with some practice, and knowledge gained when studying for the PL-200 exams, you could even go for the official Microsoft certification PL-400 - wouldn't that look good on your CV or resume? And if you are an American college student, you might even get college credit for passing that exam.
