Copilot for D365FO Development

Copilot can assist with many things, below are some areas which I explored so far,
- X++ boilerplate generation
- Documentation comments
- Plugin development using Copilot Studio
- OData integration summaries

Give suggestion on best practice on selected object or selected piece of code.

Example: Summarize Sales Order in X++

public void summarizeSalesOrder(str salesOrderId)
{
    SalesTable salesTable = SalesTable::find(salesOrderId);
    info(strFmt("Sales Order %1 for customer %2 has total amount %3",
        salesTable.SalesId, salesTable.CustAccount, salesTable.TotalAmount));
}

Best Practices (From Microsoft Learn)

Here are some tips to maximize Copilot’s effectiveness:
- Use clear comments to guide Copilot
- Keep relevant files open—Copilot uses them to infer context
- Use Inline Chat (Alt + /)
- Refer to files using #filename or /intent
- Always review suggestions for accuracy and security
