ASP.NET 5 app read/write local file in Linux ?

Hello:

I am still waiting for the ASP.NET 5 formal releasing. I have waited long time because I wanted a web app to run on cross-platforms.

I have many questions about the new ASP.NET 5 to support Linux system.

Here is the one:  Is ASP.NET 5 app possible to access local file in Linux system such as a text format file in Ubuntu ? If yes, how to do?   could share any sample code ?

Thanks!
