The summer is beginning and people are taking their well earned rest - not a huge amount of content this week and this may be the theme over the next weeks but we’ll be sure to report what we can as we can!

This week, Keith Atherton shared a cool prompt injection game to make you familiar and actually allow you to practice - so if you haven’t already, go and check out Gandalf.

🥇 Cover Story

SQL 4 CDS v10 Released

by Mark Carrington

I’ve said it before and I’ll say it again, any major update for SQL 4 CDS will always go front and centre as it’s such a powerful, game changing tool.

The impact this tool has had on my, and so many other peoples, careers is off the scale so if you’re not familiar with this tool, I would highly recommend you go and take a look.

💎 Model Driven Apps & Dataverse

When Dataverse forms don’t validate: the XSD gap in Microsoft’s standard definitions
by Riccardo Gregori
This post is actually a follow on from a previous post you may have missed: My first Dataverse MCP Server: FormEngineer where Riccardo has created an MCP server that allows communication with model driven app forms. This weeks post is a follow on and shows how much you can find out when you go real deep-diving. Both great posts and well worth your time.

How to Use setIsValid in Dynamics 365 for Effective Field Validation
by Sam Kumar
setIsValid is underutilised in my opinion so pleased Sam took the time to discuss it and show some examples this week.

by Matthew Devaney
A mainstay here at PPDW, Matthew once again pulls out all the stops and talks us through file upload with Copilot Studio - great stuff!

😎 Power Automate

by David Wyatt
When low code and pro code collide! Great post by David starting at Power Automate, working out to Cloudflare before exposing it across the Power Platform. A highlight of a read for me this week.

by Pieter Veenstra
Typings and Power Apps has never been particularly easy and solving lots of dreading warnings can take some time - Pieter guides you through his findings of that this week.
