Community Summit 2026 will be held at the Gaylord Opryland Resort in Nashville, Tennessee, USA from 11th October 2026 to 15th October 2026. I am again planning to offer Microsoft Dynamics GP Development Training during the week before the conference. Please respond to the survey below to register your interest and preference for what training class should be run.
Update: The 5 day Dexterity I course and the 1 day GP Power Tools workshop have been selected.
We are running the survey to decide which Microsoft Dynamics GP Development Training course should be offered AND to ensure that we have enough attendees to make running the course worthwhile.
Why Attend Training?
If you are wondering why you should attend Development Training for Microsoft Dynamics GP when Microsoft has announced an end of support date, the reason is simple… End of support is not end of life. There are many sites planning to continue using Microsoft Dynamics GP into the future, working with partners or community groups that will continue to support the product after Microsoft; groups such as the Knights of GP.
As time goes on the number of consultants and developers available will decrease. This makes it vital for customers and partners have their own development resources trained to be able to maintain existing customizations and code new customizations to get the most from their ERP systems.
Who Should Attend?
Everyone is welcome. While previous development experience is useful, it is not a requirement for the Dexterity I (Fundamentals Bootcamp) course. It helps if you are a user of Microsoft Dynamics GP, so you know how to navigate around the product.
Learning Dexterity (the underlying development environment that Microsoft Dynamics GP is written in) provides invaluable knowledge to developers working with the product, regardless of which language or development tools they use. This knowledge will dramatically improve the efficiency of developers using Dexterity, Visual Basic for Applications (VBA – End of Life), Visual Studio Tools for Microsoft Dynamics GP (.Net using C# or Visual Basic) or GP Power Tools – Developer Tools module.
What Courses are Available?
We have the week before the conference from Monday 5th October 2026 to Friday 9th October 2026 to run a 5-day class. There are a few options:
- Dexterity I (Dexterity Product Fundamentals Bootcamp) – 5 Day
This is an introductory course. Development background useful by not required.
- Dexterity II (Dexterity Advanced Integration Techniques) – 5 Day
This is an advanced course. It is expected that attendees have already completed the Dexterity I course (above) and have been using Dexterity for 6 months or more.
- Dexterity III (Advanced Microsoft Dexterity Development) – 5 Day
This is an advanced course. It is expected that attendees have already completed the Dexterity I course (above) and have been using Dexterity for 6 months or more.
- David’s Advanced Dexterity Workshop – 3 Day
This is an advanced course. It is expected that attendees have already completed the Dexterity I course (above) and have been using Dexterity for 6 months or more. Experience with GP Power Tools is recommended.and
- GP Power Tools Development Techniques – 2 Day
This is an intermediate course. Dexterity experience is recommended but not required. Experience with GP Power Tools is recommended.
If you are interested in attending one of these courses, please see the Course Synopsis below and then complete the survey.
Dexterity I (Dexterity Product Fundamentals Bootcamp) – 5 Day
The Dexterity I – Dexterity Product Fundamentals 5-day bootcamp course will teach you about the development environment used to build the Microsoft Dynamics GP family of products. This course will provide you with the foundation you need to build integrated, database-independent applications. In addition, you will learn how to provide powerful application functionality for Dynamics GP.
By actively participating in this class, you will learn:
- Basic programming techniques used by Microsoft Dynamics GP to develop their core modules
- How to modify existing Dynamics GP forms and reports in order to make customizations for customers
- How to develop add-on applications that will interact with the Dynamics GP products to meet specific requests by customers
- How to package and ship your dictionary allowing Microsoft Dynamics GP to make updates to Dynamics GP without affecting the developer’s dictionary
- How to register your product with Microsoft Dynamics GP using a unique Product ID to ensure no duplication of add-on applications with the same Product ID
- How to develop add-on applications that will “look and feel” like Dynamics GP and provide seamless interface between the applications to ensure a professional finished product
- How to use object triggers, which are scripts in your applications that are invoked by events in Dynamics GP, allowing several developers to deliver enhancements to the same Dynamics GP form
Note: Self-taught Dexterity developers would benefit from attending this course.
Dexterity II (Dexterity Advanced Integration Techniques) – 5 Day
The Dexterity II – Dexterity Advanced Integration Techniques (DAIT) 5-day course is designed to build upon the skills acquired from the Dexterity I course. It will provide advanced knowledge necessary to build applications that are tightly integrated with Microsoft Dynamics GP. The class will focus on building integrations associated with maintenance windows, transaction windows, inquiry windows and reports. In addition, topics such as creating SQL data and upgrading applications will also be discussed.
By actively participating in this class, you will learn:
- Advanced programming techniques used by Microsoft Dynamics GP to develop Dynamics GP modules
- How to develop add-on applications that will interact with the Dynamics GP products to meet specific customer requests
- How to develop add-on applications that will “look and feel” like Dynamics GP and provide a seamless interface between the applications to ensure a professional finished product
Note: The Dexterity I is a pre-requisite to the Dexterity II course.
Dexterity III (Advanced Microsoft Dexterity Development) – 5 Day
The Dexterity III – Advanced Microsoft Dexterity Development 5-day course will teach advanced techniques to take your Microsoft Dynamics GP development skills to the next level. It introduces many of the newer controls, APIs and features added since GP 2015. It also covers an introduction to working with Visual Studio Tools for Microsoft Dynamics GP.
By actively participating in this class, you will learn:
- How to use Tree View and List View Controls
