Hello Andrew. This is my little story. Am a 52 years old and live in Malawi, Africa. Am veterinarian specialized in production of vaccines against Tick-borne diseases. Over the years I have taught myself how to use ArcGIS, a program to produce maps, MS Access, and a few other desktop software. About 2 years ago I decided to learn C#, WPF and SQL Server. The motivation was to create a program to store and retrieve information generated from my line of work. However, the biggest motivation was to give my son a head-start as he prepared to enter college to do an IT course. Basically, I have been learning and teaching at the same time. Your videos have been a great part of that interface. l prided myself at being a very good presenter, but that was before I came across your videos. Your videos have made my "teaching" work so much easier and I have learnt a lot from the way you present your work. How I wish you would create some video lessons on advanced topics in C#. I appreciate your not been over zealous to create such videos due in part to low viewership and time constraints. I get the impression the number of views did not strike a level that would prod you to create more C# videos because a lot of people seek to view videos on topics that are not so easy to understand - Methods, Classes, Inheritance, Polymorphism, Interfaces, I am pretty sure the number of views would increase tremendously if you created such videos and it will leave a lot of people very happy and ever appreciative of all the works you have done and will continue doing. You are simply a gifted teacher and who enjoys what they do.

Stay blessed.

Hello Andrew, what we need to do in order to make you continue this series to become a complete one like excel vba ???
(Regardless if it’s for free or no )

Why have you stopped this playlist? It was so useful.

[HenriqueVCosta]

Could you please tell me where do you explain about 'constructors' in C#, i mean, in which video of all your playlist? Thank you. Keep up the good job. in data base you are 100 times better than my actual Diploma teacher.

Probably good video for beginners. Slow phased and few details given.

33:33 "finally block is literally the final thing that happens in a method"
i think that is wrong to say that! it can continue after finally, but u got return in a catch block. so my guess is that before returning compiler cleans up with finally and then returns. remove return from catch block and code should continue after finally.

try this code... and then uncomment statement in try block and try again.... code continues after finally.
(but if u insert return in catch then it will not continue after finally if exception is thrown)

using System;

class Foo
{
public void Boo()
{

try
{
//throw new Exception();
}
catch (Exception e)
{
Console.WriteLine("Cached exception");
}
finally
{
Console.WriteLine("Finally");
}


}
}

class Program
{

static void Main(string[] args)
{

Foo f = new Foo();
f.Boo();

Console.ReadLine();
}
}

+WiseOwlTutorials Hi, can you do some more C# videos please?
I passed my 70-461 Querying SQL Server exam, and I attribute that almost entirely to your videos :)
