Typically to get my bearings on Web Frameworks, I build an Amazon clone. Why?
* I can use the frameworks "partial views", header, footer, sidebar.
* I can use the frameworks stylesheets/javascript/images helpers.
* I can see how file uploads work (let users upload avatars).
* I can see what forms helper the frameworks have "create product" form.
* I can see how the framework facilitates forms validation.
* Search - I can see what ficilities the framework gives me in filtering rows from the database.
Once I'm done with this simple app, it takes me around a day, I can confidently say I can work on actual products.
