Hello everyone. My name is Furkan Gözükara, and I am a Computer Engineer Ph.D. Assistant Professor at the Software Engineering department.

In this course, starting from ground to the advanced level Object Oriented Programming concept and the C# programming language will be taught.

This course requires you to have fundamental knowledge about programming in C#. If you do not have, you can watch our Introduction to Programming with C# course playlist : https://www.youtube.com/playlist?list=PL_pbwdIyffskoSXySh0MdiayPJsBZ7m2o

** In lecture 14 we have shown the following topics:

* How to use inheritance to derive Entity Framework automatically generated (data to code approach) class to set default values of database tables
* How to convert a derived class object instance into a base class object instance automatically with JsonConvert.DeserializeObject and JsonConvert.SerializeObject (Newtonsoft.Json). Thus, a derived class instance can be saved into a database with Entity Framework
* How to use Microsoft SQL Server Profiler to check, analyze and tune Entity Framework database queries
* How to achieve synchronization when working on a multi-threaded C# application by using tasks of Task.Factory and DispatcherTimer
* How to use System.Windows.Threading.DispatcherTimer to achieve polling effect and periodically execute a method
* How to start a certain number of concurrent tasks to crawl web pages concurrently
* How to use ContinueWith of tasks to take certain action after task completed
* How to do html decoding properly
* How to improve application performance with ThreadPool.SetMaxThreads, ThreadPool.SetMinThreads, gcAllowVeryLargeObjects enabled="true" and gcServer enabled="true"
* How to improve the concurrent crawling speed with ServicePointManager.DefaultConnectionLimit
* How to use ObservableCollection to automatically update / refresh elements on the user interface, such as a ListBox
* How to design and code / program a fully functional, fully multi-threaded, robust web crawler from scratch
