I need some advice

I want to attempt to make an isometric based game. I sooner or later would like to also make a isometric online community (Sort of like habbo or any other isometric game you can think of). The problem is I have no past experience in any of this. I want to build it in C# the only language i've ever tried was python but didn't get too far with it. I've only copied examples out of books none of it was my own. So I guess you can say all I know about real programming is the logic that goes into it. I know it takes time to build what I want to build. I know I'm not going to be able to do this for maybe years but i would like to atleast get some book names maybe for C# that could help me begin programming it. I have all the necessary tools to start. Just don't know where to start.
Please help
