What should I need to start game development with Unity?

I have been developing Android applications and also used to work with Java on Ubuntu. I am new to game development, I just installed windows 10 and Unity 5.0

Surfing over the internet I came to knew that Unity uses either C# or JavaScript for development. I'd choose C#.

What are the things I need to install to start development in Unity. I mean do I require C# library and/or IDE for C# or just installing Unity is all I required? If I still need to install anything then please provide the link to download.

 

Unity comes with Mono Develop as an IDE, but I recommend grabbing Visual Studio Community (you need UnityVS too).

 

Thanks for the reply, I'll download the IDE you suggested but don't I need to download C# libraries? Without it how would Unity compile the script?

P.S. I do not have Visual Studio or anything installed in Windows.

 

Unity has its own compilers and libraries included.

 

Just grab Unity. It comes with everything you need to get started.

 

I installed Unity 5.0 and just start a new project but when I click on any .cs script, windows pops a window to select any application to open this type of files and that means my computer hasn't any program to open C# script.

If Unity comes with everything required then please tell me how can I open .cs script and edit it and apply to the object.

 

Did you install MonoDevelop when you installed Unity? It should install automatically and sync up by itself.

 

Yes, I installed MonoDelevop but I didn't install Microsoft Framework maybe that's the reason I can't open .cs files. Let me check what happens after installing ms framework.
