Starting in August 2026, the planned changes to the subscription model for 2027 for Visual Studio Integration Toolkit (VSIT) have been taking effect.
This article explains how those changes effect customers and partners of the product and hopefully answers any and all questions you might have. This article has been added to the VSIT Portal: https://winthropdc.com/VSIT
Winthrop Development Consultants is pleased to announce Build 21 of Visual Studio Integration Toolkit (VSIT) for Microsoft Dynamics GP was released on 21-Apr-2026.
This build includes minor fixes and support for the subscription model changes coming in 2027.
Winthrop Development Consultants is fully committed to the continued support of Microsoft Dynamics GP and its ecosystem. Our ISV products are only compatible with Dynamics GP and have been created to solve pain points and missing features as requested by the GP community.
While Microsoft has stated that they will cease support for Dynamics GP in 2031, it is important to note that “End of Support” does not equate to “End of Life”. There is plenty of life left in the product and, with the support of the community, GP will live on well past the official end of support. A driving force in the community support will be the Knights of GP.
Visual Studio Integration Toolkit provides Application Programming Interfaces (APIs) to Visual Studio Tools for Microsoft Dynamics GP developers adding functionality that is normally only available to Dexterity developers.
For almost 20 years the application menus feature has been available at no charge as Menus for Visual Studio Tools from Microsoft and later Visual Studio Integration Toolkit from Winthrop Development Consultants. This was David Musgrave’s gift to the Microsoft Dynamics GP community. Sadly, as the cost of maintaining and supporting the product increases, it has become necessary to charge a small fee for subscriptions starting in 2027.
When GP Power Tools Build 32 was released, it added powerful Custom Table functionality which allows for a developer to create a custom table definition and have that table created in each company automatically. The table can then be used in a similar fashion to a native Dexterity table using a suite of Custom Table Buffer Helper Functions.
This article updates the original article (below), which explained how to create a Custom Forms Module demonstration project, to use Custom Tables instead of SQL Tables for a much faster and simpler implementation.
The next version of Microsoft Dynamics GP has been released, and it contains more new features and bug fixes.
Winthrop Development Consultants has already updated its products for this Microsoft Dynamics GP 18.8 – October 2025 release. They are now built against the final build and so are no longer beta builds.
Check out the previous article for more information:
A recent customization project I was working on using GP Power Tools required the calculation of a square root as part of some number crunching needed to work out material quantities on a Sales Order Processing transaction.
While Dexterity (the language behind Microsoft Dynamics GP) is great at accounting style mathematics (as per a standard calculator), it does not have advanced functions for powers, logs, and trigonometry (as per a scientific calculator). This means that there is no “native” method to calculate a square root.
However, Dexterity (from v14.0 onwards) has a .Net Interop which allows you to import and call .Net libraries directly from your Dexterity scripts. This example shows how to call the System.Math library as well as other advanced techniques, such as Custom Forms and Virtual Fields.
Good News for the Microsoft Dynamics GP Community.
Friday morning (Perth Time) I had an email from Terry Heley from Microsoft with a link to a pre-release (ISV Drop) of the upcoming Microsoft Dynamics GP version 18.8 (October 2025) release. This download is provided to the ISV community to help them prepare for the final code when it is released.
