not found InitializeExtDesign.xpp

I created an Add-On form. But it's not working.

As one of the causes, when you debug the Add-On form,

the message "Form.FormName. = InitializeExtDesign.xpp not found" is displayed.

What should I do to solve this? We need your cooperation. Please.

    Hi Keito,

    Please try to build your project and model and check if the file exists in C:\AOSService\PackagesLocalDirectory\Bin\XppSource.

    Please make sure that you do not have the setting checked to load only symbols in your solution and and restart IIS.
