A new macro management tool replaces the IDE used to create and manage macros in previous versions of Revit.
The macro management tool allows you to create and run macros using Visual Studio Code. The macro manager no longer supports file based macros. To use existing file based macros you must first convert them to application based macros. See Upgrading Revit Macros for instructions on upgrading existing macros for use in the Macro Manager.
For more information on using the macro manager to automate tasks, see the topics under the heading Automating Tasks with Macros.
