About the MB-500 exam
MB-500 is the exam for developers who build business logic, reports and integrations in Microsoft Dynamics 365 finance and operations apps, mostly in X++. Its skills run from Lifecycle Services and Azure DevOps through AOT elements, code and testing to data integration, security and performance. Microsoft expects deep knowledge of the app's framework, data structures and objects, and experience with tools such as Visual Studio, Postman and SQL Server Management Studio. Passing earns the Microsoft Certified: Dynamics 365: Finance and Operations Apps Developer Associate certification.
The PlanetCert practice test puts the most questions on AOT elements and X++ code, with data integration and performance close behind. Its explanations show why one extension pattern works and another fails, such as a Chain of Command wrapper that must call next. Study Mode suits the security and performance questions, where duties, privileges, caching and set-based queries are easy to confuse. Brainy AI Assistant can explain when dual-write fits better than virtual entities, or how an XDS policy filters records.

How to prepare for MB-500
- 1
Get a development environment
Set up a finance and operations development environment with Visual Studio and the developer tools. Every task in the skills outline is easier to learn by doing it once.
- 2
Extend standard objects first
Add a field to a standard table, show it on a standard form through a form extension, and fill it in a Chain of Command wrapper. These steps touch most of the AOT and X++ topics.
- 3
Build one batch job end to end
Write a SysOperation job with a contract, a controller and a service class, add a SysTest unit test, and run it in Test Explorer. Then trace it with TraceParser and look for slow queries.
- 4
Move data in and out of the app
Import a composite entity through a data project, then expose the same data through OData and a business event. Compare dual-write and virtual entities: what each one copies, and when.
