Business Rules vs. Client Script. Business Rules work on the Server (mostly). Client Script works only on the Form. If you import data via API, Client Script won't run. Business Rules (usually) will. For data integrity, always prefer Server-side logic.
XrmToolBox "Attribute Usage Inspector." Ever wonder "Can I delete this field?" This tool tells you exactly how many records are actually using that field. If it's 0% populated, delete it. Keep your schema clean.
Solution Checker is your best friend (and worst enemy). Run it before you try to export. It catches the silly stuff: "Retrieving all columns," "HTML in labels," "Deprecated client APIs." Fix the warnings now, or fix the bugs in Production later.
Ribbon Workbench. It’s still the only way to reliably customize the Command Bar in Model-Driven Apps. If you are trying to edit the XML manually, you are brave (and foolish). Support Scott Durow (the creator). Buy him a coffee. ☕
Dynamics 365 "Dual Write" vs "Virtual Entities." Dual Write copies data (Double storage, tight coupling). Virtual Entities reads data (No storage, loose coupling). Unless you need heavy querying logic on the D365 side, default to Virtual.
