Add custom fields to SalesTablefeature/sales-custom-fields
Add two custom fields to SalesTable in the Contoso Retail workspace: ContosoDeliveryPriority (enum, default Standard) and ContosoStoreId. Show them on the sales order header and validate that the store exists.
Done. I extended SalesTable with both fields, added the enum, placed them in a new Contoso group on the header, and added validateContosoStore(). Deployed to your UDE; one test failed, fixed it, all 18 pass.

Pick a codebase, pick an environment, ask.

Every conversation is pinned to one connected codebase and one connected environment. FOFox works on that repository and deploys to that environment, and the chat shows exactly which pair it's using.

Hello! I'm your D365FO copilot.

I can help you with development, configuration, troubleshooting, best practices and more.

Your codebase

Connect your own codebase. FOFox works inside it.

Sign in with Microsoft Entra ID, pick the Azure DevOps repository, and tell FOFox where your project and models live. From then on every answer and every change is grounded in your actual code, not generic D365FO.

Your dev environment

Deployed and tested in your own UDE, before you look at it.

FOFox gives you a dedicated account for each environment. Add it as a user in your Unified Development Environment once, click verify, and you're connected. After that, every task is built, deployed to that environment, tested and debugged there, so the code you review has already run in a real D365FO instance.

FAQ

Questions partners ask first.

Does FOFox store our source code?

No. Your Azure DevOps repository stays the source of truth. FOFox keeps only what a review needs: changed files, the patch, logs, build output and test results.

How do you handle DevOps credentials?

You sign in with Microsoft Entra ID and grant FOFox the Azure DevOps permissions it needs. FOFox never asks for your password or a personal access token.
