SteadyCode has published a slightly modified version of the Microsoft Dynamics SL SDK project template, modified so it’s a Visual Studio 2026 extension. It also works with Visual Studio 2022.9 and higher. If you have both VS versions installed, the extension will offer to update both. You can download it here.

Version 2022.9 or higher is required because Visual Studio became a 64-bit application with VS 2022. That broke the Windows Forms designer until the team created a 32-bit out-of process designer. Version 2022.9 had that and was released on Feb. 29, 2024. If you have the latest VS 2022 version installed, this project template will work.

When you install the extension, all the controls for the Dynamics SL SDK will be included in the toolbox, as shown below. You will need to enable the out-of-process designer when asked. In the past, it was necessary to run two “vsix” projects to have the full SDK project, including the toolbox controls.

As of Nov. 21, 2025, the extension is in preview. Please provide any feedback in the comments for this post. When it’s no longer in preview this paragraph will be removed and any changes from the initial preview release will be noted here instead.

SteadyCode continues to support customers who are running Dynamics SL, and work has increased as customers integrate with other systems while preparing to move the financial and other modules to other ERP solutions.
