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.

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.
Winthrop Development Consultants is pleased to announce Build 20 of Visual Studio Integration Toolkit (VSIT) for Microsoft Dynamics GP was released on 20-Jun-2025.
This build includes enhancements to the table update processing and general maintenance fixes.
Today, we have an interesting support case where the installer for a Winthrop Development Consultants product failed to complete with the following error message:
Update now to the latest builds for your version of Microsoft Dynamics GP.
This article provides advanced warning that old builds of Winthrop Development Consultants products for versions GP 18.0. or later will be discontinued at the end of August 2025 and will no longer be able to renew their subscriptions.
It is vital the customers update their installs of our products to get all the new fixes, features and enhancements that their annual subscription entitles them to.
Winthrop Development Consultants is a proud member of the Microsoft Dynamics GP community and we continue to invest in the community we love by being a sponsor at three upcoming conferences, the first starting in a week’s time:
In preparation for these conferences, we have used the great video creation tool, Renderforest, to update our product introduction videos for our latest builds and create a video for the amazing new GP Power Tools – Form Control module.
The latest and greatest version of Microsoft Dynamics GP has been released, and it contains many new features and bug fixes.
Winthrop Development Consultants has already updated its products for this Microsoft Dynamics GP 18.7 – October 2024 release. They are now built against the final build and so are no longer beta builds.

Here is a quick project that can make using Microsoft Dynamics GP much easier for your users. We are going to use GP Power Tools along with the free menu module of Visual Studio Integration Toolkit to add windows to the application level navigation menus.
For our example we are going to use the Professional Services Tools Library and add a menu to the main window of the product as well as the Receivables Transaction Unapply window.
[Edit] We are also going to add the Item Reconciler window as that requires some different techniques.
A couple of weeks ago, we had an unusual support case: upgrading two of our products, Visual Studio Integration Toolkit and GP Power Tools, was failing with a SQL Server error I had never seen before.
The errors only occurred on the customer’s live system, but the install worked fine on their development system. Eventually the cause for the issue was identified.
Today, my good friend Beat Bucher, had the same error and I was able to tell him the cause straight away. Read on for a full explanation.
We are currently seeing an increase in customer sites reporting the Registration Expired or Failed dialog when launching Microsoft Dynamics GP.
This dialog is to notify users that a Winthrop Development Consultants product is no longer registered and action needs to be taken by the system administrator to fix the subscription and restore the product’s functionality.
Winthrop Development Consultants is pleased to announce Build 19 of Visual Studio Integration Toolkit (VSIT) for Microsoft Dynamics GP was released on 19-Jan-2024.
This build includes enhancements to the new Custom Forms module along with improvements to the installer systems. The User Guide Manual has now grown to 95 pages, plus their code examples and sample project also provided.
This article covers how to uninstall Winthrop Products and also how to remove previous versions showing in Programs and Features in the Control Panel.
Winthrop Products use a two-step uninstall process and will not uninstall from the Programs and Features applet in the Control Panel until they have first been uninstalled from the Microsoft Dynamics GP application. This allows the products to clean up all the settings, tables and other SQL objects from the SQL Server as well as removing themselves from the application installation before the files are removed by uninstalling from the control panel.

We are seeing more and more sites realizing the potential of using GP Power Tools – Developer Tools module as their platform for custom development for customizations, tweaking and fixing behavior of code within Microsoft Dynamics GP.
Many customers are using GP Power Tools (GPPT) to replace their unsupported Visual Basic for Applications (VBA) customizations, which is great as GPPT is the best solution for replacing VBA, Dexterity and Visual Studio Tools addins. It offers many benefits over other development tools.
