I started building an application using ASP.NET Boilerplate, and as I am getting familiar with the framework I am considering a move to the paid ASP.NET Zero version. I would like to assess the effort to migrate code, as it is a big code base. Looking at n-layers, there are some differences in backend code but still manageable. However, the challenge I feel is in the UI as ASP.NET Zero is tightly coupled with the Metronic UI, and I am utilizing Kendo UI in my application.

I tried to download a cracked ASP.NET Zero version online. I followed the instructions:

• replace the cracked file in the nuget folder.
• run yarn at root application.mvc project.

The solution and all projects build and compile fine, but I am faced with an error in the browser.

Uncaught ReferenceError: app is not defined

 var _tenantChangeModal = new app.ModalManager({
    viewUrl: abp.appPath + 'Account/TenantChangeModal',
    scriptUrl: abp.appPath + 'view-resources/Views/Shared/Components/TenantChange/_ChangeModal.js',
    modalClass: 'TenantChangeModal',
    modalSize: null
});

I am not familiar with Node.js nor Angular, I use jQuery. This might be a simple fix as I might be missing something, or a bigger thing that requires further investigation.
