Browse the Entire D365 F&O AOT and Edit X++ — No SQL Server, No Visual Studio

Introduction

If you work with Dynamics 365 Finance & Operations, you know the ritual. You want to look at how a table is used, or read a class, or check a security role — and somehow that means spinning up a cloud-hosted dev box, opening Visual Studio, and (if you want cross-references) restoring a multi-gigabyte DYNAMICSXREFDB first. A five-minute question turns into an afternoon.

The latest release of FinOps Workbench — our free tool for the Dynamics 365 community — sets out to remove that tax. v1.0.16 adds a complete AOT browser and a compiler-accurate X++ editor, and it does the whole thing from an environment's metadata: no SQL Server, no DYNAMICSXREFDB restore, and no Visual Studio.

The whole AOT, indexed from metadata

Point FinOps Workbench at an environment and click Get sources. In one operation it downloads the environment's PackagesLocalDirectory, extracts it, and builds a local object index — and every step resumes where it left off, so the same button doubles as "continue where it stopped." Already have an extracted copy on a build VM or a mounted VHD? Point straight at it with Browse folder… and skip the download entirely.

Because the index is built by sweeping the metadata files themselves, the tree holds the complete Application Object Tree — a stock application lands at around 240,000 objects. That includes the pure-metadata types (security objects, menu items, EDTs and the like) that a cross-reference database barely covers. You get Classic view (the familiar Visual Studio categories) and Model view (grouped by package), a search box that finds any object by name across the whole tree, and read-only Design trees for forms and tables with a property pane — the structure you already know.

Find references without an xref database

The feature that usually forces the DYNAMICSXREFDB restore — Find references — works here straight from the local index. Select any object and see what it uses and everything that uses it, and double-click a row to jump to the referencing object. No SQL Server instance, no restore, no waiting. On a stock CustTable, that is comfortably 500+ symbols resolved in a click.

That single change is the difference between "I'll check the xref later" and just checking it now.

A real X++ editor — colouring, go-to-definition, IntelliSense

Open any object and it lands in an X++ editor whose parsing is derived from the actual X++ compiler, not regex highlighting. Classes, interfaces, tables/views/entities, EDTs and enums are each coloured by what the index knows they are; keywords, literals, macros, intrinsics and labels all render like Visual Studio. Press F12 on any identifier to jump to that table, class, EDT or enum. Every object opens in its own tab that remembers its edits and cursor position — pin them, close others, the usual.

And you can edit your own models. Objects in a custom model are editable right in the viewer (standard Microsoft code stays read-only), with IntelliSense as you type: object names, your variables with their declared types, Type:: static members and enum values, and variable. members resolved through the type's full inheritance chain. Save writes your method changes back into the metadata XML precisely — only the code you touched changes — so the file diffs cleanly in Git.

To keep us honest: editing is for custom-model objects only, form data-source/control code is view-only for now, and the tool doesn't compile or deploy. It's for reading, understanding and making targeted code edits — fast.

It still does everything else — and it's free

The AOT browser joins what FinOps Workbench already did: see your whole D365 estate (F&O, Customer Engagement, UDE, LCS and Dataverse) in one grid; request just-in-time SQL access and query any F&O/UDE database in a built-in SSMS-style workspace; download VHDs and LCS assets; trigger DB syncs; and drive the whole thing from Claude through a built-in MCP server. No dev box, no Visual Studio — and, yes, it runs on macOS as well as Windows.

It's free, it signs in with your own Microsoft account (no app registration, no client id or secret), and on Windows it's now a one-click install from the Microsoft Store with automatic updates.
