Development and customization

Feature Why this is important
EventHandlerResult classes in request or response scenarios You can now use the EventHandlerResult class for scenarios where the delegate (event) logic requires its subscribers (event handlers) to provide at least one response so that no result is lost when there are multiple subscribers and multiple results.
Customization Analysis Report (CAR) justification When you suppress a best practice warning within a suppression file in the AxIgnoreDiagnosticList folder of your model, and include a justification, the justification text will appear in the CAR report of your model. For an example of a suppression file that includes justifications, see <Packages Local Directory>\Directory\Directory\AxIgnoreDiagnosticList\Directory_BPSuppressions.xml.
Telemetry When a model is built, the telemetry framework collects information about Microsoft classes and methods that are referenced by customer and ISV code. This provides Microsoft with much needed information regarding what part of the standard application code is included in backward compatibility requirements.
X++ compiler and try catch blocks The X++ compiler now generates code that is slightly different for try catch blocks. Before, the system would catch the DuplicateKey and UpdateConflict exceptions as part of the catch all clause. This introduced some problems that could ultimately lead to data consistency problems if the try catch was used when a transaction is running. Now, the two exceptions mentioned, which are special because they do not roll back a running transaction, are no longer caught in the catch all. For more information, see the blog post X++, the catch.


Feature Why this is important
Enhanced administration features for personalization The personalization administrator can now apply or remove form personalizations for groups of users. Previously personalization administration was only possible one user at a time. For more information, see Personalize the user experience.
