AL Language extension for Microsoft Dynamics 365 Business Central version 15.0.1433841 (New version)
The AL Language extension version 15.0 introduces implicit conversion between Record and RecordRef, HTTP mocking for testing, improved JSON data access methods, multiline strings, a continue statement for loops, and numerous other developer features. This update helps developers write more flexible, testable, and maintainable AL code with enhanced language constructs and APIs.
post Gerardo Rentería Blog
"Every HTTP request that occurs during the execution of that test will be intercepted and routed to the handler."
Key points
- Implicit conversion between Record and RecordRef types allows direct assignment without explicit method calls
- HttpClientHandler enables mocking HTTP responses in test codeunits with configurable request policies for OnPrem instances
- New JSON access methods (GetBoolean, GetInteger, GetText, etc.) simplify data retrieval without always using JsonToken
- Language enhancements include multiline strings with @ prefix, continue statement for loops, and UserControlHost page type
- Multiple developer experience improvements in VS Code including searchable downloaded symbols, new project templates, and file preview functionality

- “From runtime version 15, it is possible to use the continue keyword in loops to continue to the next iteration.” (Adds a standard loop control feature that developers expect from modern programming languages)
