Course Description

Extension methods were introduced in C# 3 and since then became an indispensable part of the .NET platform. That enormously powerful feature allowed to build a whole framework built upon it called LINQ or Language Integrated Query. I’ve seen many code bases which avoid using LINQ and rely on old procedural style of programming. If you still feel yourself uncomfortable with LINQ or you want to improve your understanding of LINQ, then this course is for you.  As you might know, LINQ was inspired by functional paradigm and F# in particular. So, this course is not only about LINQ but about the fundamentals of functional programming as well.

This course covers:

  • The basics of LINQ: extension methods, the idea of pipelining, IEnumerable, implementing our own extension, query syntax, pitfalls of LINQ operations, how to alter a list

  • Generating data streams: Enumerable class and its main operations, implementing your own extension which generates a stream of data

  • Filtering, Ordering, Projecting: Parsing a CSV file, ThenBy, First, Last, Single, TakeWhile, SkipWhile,Any, All, Contains, SequenceEqual, Select and SelectMany

  • Joining, Grouping, Aggregating: Join, Group, GroupJoin, Zip, Sum, Average, Min, Max

  • Conversions: OfType, Cast, ToArray, ToList, ToDictionary, ToLookup, AsEnumerable, AsQueryable

  • LINQ to XML: overview, generating XML from a collection, reading XML

  • EF and LINQ: Expression Trees, Inserting  into and Reading from a database

  • Extendibility in C#: what is functional programming (FP), purity and side effects, extending IDisposable, general-purpose extensions, extending StringBuilder, Primitive Obsession

In short, this is a great course, so enroll right now and start learning LINQ and the fundamentals of functional programming.

I finished the course, I would like to note that the topic of LINQ is covered perfectly. Other additional topics were also covered and some pitfalls in certain code implementations were solved.

Example is being mismatching and bit confused .. navigation is creating difficulty to understand in well manner. Tab navigation should be lesser while practical example to have a mature understanding.

Der Kurs ist wirklich super. Es wird alles ausführlich erklärt. Das schöne ist, dass die Videos sehr kurz sind, dadurch hat man den Vorteil, wenn man etwas nachschauen möchte, kommt man schnell an die gewünschten Informationen. Man muss nicht in langen Videos suchen.

Very good instructor, with concepts that are too many interesting, also the examples are good for practicing and debugging, you learn in this course a lot.

By Ronaldo Peres on 11/19/2020

Very good content in this course. Some parts could be better explained, as they are advanced content and I know there is a lot of programmers that can get lost.

The course was highly informative I laerned so much. I wish more was said or tought in the linq to entities especially combininit with asp.net MVC as this would give more insight. I learned a lot and am happy.

By Cathy Dopp on 3/23/2020

The examples really helped clarify patterns that I've encountered in a huge project I've inherited. (And your English is excellent too.) Спасибо

Good course. Audio could be beter at some points. (volume to low) and the audio is sometimes only on the left channel.

By Anonymized User on 7/31/2019

The author has a profound understanding of the topics and brings useful and real examples to illustrate the main concepts of what is being taught.

By André Torres Corrêa on 6/24/2019

This course goes beyond just Linq, it also gives you a bit about functional programming and extension methods in C#. The linq part is great, but the functional paradigm is a bit more complex, and I needed to watch more than one time to get it.
