The first standalone, AI-native IDE for Microsoft Dynamics 365 F&O.
Core Studio
“First” — after an exhaustive review of the market · see the map
Build X++ with a development environment designed for the whole F&O system.
Core Studio brings code intelligence, guided creation, build and release workflows, and human-controlled AI into one focused workbench for Microsoft Dynamics 365 Finance & Operations.

Watch real workflows Explore Studio FeaturesThe trial and download lifecycle is being proven end-to-end. Watch the product in the demo; Contact Sales for evaluation access.
One workbench, four workflows.
Understand, change, verify, and get assistance — against the same indexed model of your F&O application.
Understand
A workspace-wide map of code and metadata: navigation, search, and the AOT explorer answer from the indexed application.
Change
Edit X++ with diagnostics as you type, or scaffold extension-first changes through guided wizards with review before build.
Verify
Run the Microsoft toolchain — compile, database sync, deployable package — and supported test workflows from one visible pipeline.
Assist
Governed AI reads the indexed workspace, proposes changes, and stops mutating actions at a human review gate.
The complete engineering loop.
Each stage names its tool, its output, and its failure state — streamed, not hidden.
-
Understand
Index the application catalog in tiers; early results are visibly partial while deeper tiers complete.
-
Edit
Diagnostics, hover, and cross-model navigation while you work; wizards scaffold into the correct model.
-
Build
Core invokes the supported Microsoft build components and streams the compile with an explicit verdict.
-
Test
Run supported .NET and X++ SysTest workflows; jump from a failure to its source.
-
Package
Produce a deployable package with the documented structure; validation stays with Microsoft's tooling.
-
Release
Generate CI pipeline artifacts for your Azure DevOps environment; release execution stays in your pipeline.

Studio Features.
Every listed capability is live in the current build and documented.
Build, sync, package, release
Run the Microsoft toolchain stages — compile, database sync, deployable package — from one visible pipeline.
Start a build; each stage streams its output and stops on failure.
C# companion projects
Build net48 interop libraries, net8 OData clients, and Azure Functions beside the F&O model.
Add a companion project; build, test, and debug it with the X++ workspace.
X++ editor and diagnostics
Edit X++ with diagnostics as you type, hover information, and cross-model navigation.
Open a class; diagnostics and hover resolve against the indexed metadata.
Environment profiles
Switch AOT roots between environments with per-profile state preserved.
Define profiles for local editing, OneBox, UDE, or CI roots.
Source control
Stage, commit, and inspect changes in the built-in Git panel.
Changed files group by status; stage and commit in place.
Global source search
Ranked search across names and source text with snippets, filters by name, type, model, and property.
Query by name or code text; results carry snippets and model scope.
Governed AI assistant
AI tools read indexed code and metadata, propose changes, and route mutating operations through an approval gate.
Ask for a change; mutating actions stop at a human review with a full preview.
Guided creation wizards
Scaffold tables, forms, classes, and more through extension-first wizards with review before build.
Pick a wizard, answer the steps, review the generated artifacts, then build.
Workspace-wide index
The application catalog is indexed in tiers so navigation, search, and AI tools answer from the real metadata.
Open a root; the index builds in tiers with partial results flagged while deeper tiers complete.
Report design
Edit SSRS report structure and layout with the rendering boundary stated: real data rendering happens against the target environment.
Open a report, edit its structure on the canvas, deploy and execute for rendering.
Test workflows
Run supported .NET and X++ SysTest workflows with one result model, history, and failed-test navigation.
Discover tests, run them, jump from a failure to its source.
