Is there any way to use ShopifySharp to create Theme App Extensions

[candreouTrade]

Hi,

I recently bought the Book from Josh and have created a script tag using Shopify sharp. The Shopfy team will not approve the app without a Theme App Extension. I don't recall seeing how these extnsions can be created in the book. Is there an example on how to create these Theme app extensions when using .NET and ShopifySharp?

Ideally an example that shows how to go from a script tag to a Theme app extension as a new Chapter/Blog Post covering this.
