Does Visual Studio conceal some details of execution environment of c#?

Does Visual Studio conceal some details of execution environment of c#?

I am very new to c#.I started c# today.I don't know execution environment
of c# very well.
I can explain my question more by taking netbeans as example.
When we create JSP project in Netbeans then it creates web.xml by itself.
This file is needed to deploy the project.So if we want to create JSP
program without using netbeans then we have to create web.xml by ourself.
So my question is does VS also create files by itself that are very
neccessary to run C# program?

Thanks
