Play C# Fundamentals for Absolute Beginners: (18) Understanding Namespaces and Adding References to Assemblies
Description
In this lesson, we explain how Namespaces allow us to disambiguate classes that may share the same name. And we explain how the .NET Framework Class Library is so large that including all its classes in every application you write is a waste of system resources. Certain project templates include references to the typical assemblies required by a given type of application, and we demonstrate this by referencing a custom assembly of Bob's own design.

The Discussion
-
gwkmah Hi Bob,
Where can I download the Tabor.dll file from?
Garry
-
topgearlmh @gwkmah:in the zip of codes
-
phinity @topgearlmh - maybe a noob question but where is said 'zip of codes' I dont see a link to it anywhere on this page
-
noobnr2 @gwkmah @topgearlmh Same here, can't see any zips on the page at all.
-
NurkaSnegurka For the source code files, go to the older tutorial of C#... at this link:
https://channel9.msdn.com/Series/C-Sharp-Fundamentals-Development-for-Absolute-Beginners
and click on "Download the entire series' source code" link. Tabor.dll file is in C9CS_17 folder.
P.S. Bob, great series! Thank you!!!

TheSpecialist Hi Bob,
To my understanding the entire concept of the 'using' statements is to save us from writing code as you demonstrated in the video.
but i also noticed that you have the following statement in your example
using System;
but you still use the 'System' namespace in the following line of code:System.IO.StreamReader myStreamReader = new System.IO.StreamReader();
why do you still need to use it if it is already declared in the beginning?
-
BobTabor @TheSpecialist: Why do I still use it even though it is already declared in the beginning? Good question. The answer is the *technically* I don't have to. However, *practically* I choose this "style" because it is expressive. If you are new to .NET, it would still be obvious to you the full namespace where the:
IO.StreamReader
... is coming from. I am explicit in these cases for others who read my code (and heck, for myself ... I'll have to read that code again someday!)
So, in short, it's simply a style preference.

Vahe13 HI Bob,
First of all thank you for such a interesting and detailed lessons for beginners! You are cool!
I have 2 questions:
1. if (Can I use .NET libraries when I work with Unity3D) how? ;
2. how can we create our own libraries?
Thank you!

Tom Bob,
Thanks for these tutorials. How would I include a source file I made, that exists in the same directory? -
Tony11B Hey thanks Bob for the awesome videos!! Just started learning about C# not too long ago.

yahya Hi Bob,
Thank you so much for all of your series of tutorials, I can't never get enough, even when repeating them over and over again I never get bored!
My question is:" Can we consider namespaces in C# as Headers in C/C++?"
