Hello! I am an absolute begginer with windows phone app developing and developing in general. I have watched some videos for introducing me with programing but i have an specific idea and don't know where i need to star to learn. I want to create an app that show to user a website, but not the full website. i want to catch the post, post titles, categories and images. I only need a quiq tutorial for doing such thing, after that i will be able to discover by myself. Thanks
So, you're going to want to learn C# if you haven't. That will probably give you some ideas on how to extract data from websites.
For Windows Phone development, C9 has a great beginner series for that.
