the status of networking tutorial and code

Hello

I am new to unity world I want to inquire the status for networking script and tutorial which is available at unity site my question is:

Is that code is compilable as I have couple of times tried to compile via several ways but its showing lot of errors ...

Is it also possible to compile each project as a single project for simplicity or whether that is not possible because of dependencies

or whether that code is still valid ?

Can somebody all ready go through with code and compiled those projects.

Please share your experience.

How to compile each project separately or together?

BR,

Jibbylala
