I’m trying to extend a standard table in Visual Studio to change a property.

When right-clicking the object and selecting Create extension in new project, on the Configure your new project dialog Visual studio throws a System error when I click the Create button.

The message just says System error with no other information given.

This is happening on two different VMs, one of which is on F&O version 10.0.40 and the other is on version 10.0.41.

On the VM, the folder for the project and solutions are created under C:\Users\Adminxxx\source\repos but the folders remain empty and the object I want to extend is not added.

The same issue occurs when I tried to extend other standard objects like Data entities, EDTs, etc.

As a test I tried to extend the CustTable table (which we’ve already had an existing extension on) and the same issue occurs.

The extension artifacts should end up in the model's folders in PackagesLocalDirectory, not in the repos folder.

Have you created a model for customizations, and you see your customization model in the machine?

The solution/workaround:

In the AOT search for any object in your customisations model.

Add this item to a new Project and create your new project in the Configure your new project dialog in Visual Studio.

With the new project open in the Solution Explorer you can add standard objects extensions to the project.
