Course details

Want a simpler, more consistent way to query data ? Language-Integrated Query (LINQ) may be what you're looking for. This general-purpose query toolset allows allows developers to filter, sort, aggregate, and query data directly within C# code. In this course, join Walt Ritscher as he helps you get up and running with LINQ, focusing on LINQ to Objects. Walt begins by showing how to use LINQPad, the code editor and code runner you can use to write and test the LINQ examples provided in this course. He then highlights the key .NET features that power LINQ, the essential elements of a query, and the different types of query expressions. Plus, learn about filters, aggregates, groups, element operations, quantifying data, and partition tools. Along the way, Walt provides challenges that help you grasp how to apply these concepts in the real world.

    Query Expression, Extension method and bit of lambda expression... These give flexibility in linq. At the same time, they create complexity. There are many ways to wrtie/declare instructions for the same intention; a lot more than traditional sql query. Linq's instruction called "expression" than "query". If tsql hides internal complexity by declaring intention of programmer in certion way, linq hides ever more detail with short amount script. Linq expression is more like definition than declaration. If Linq used without knowdlege of database archtecture behind, it's easy to expericence pereformance issue. I hope AI takes portion in performance optimization in linq, since I had too many time converting linq to sql to resolve the performance issues.

    I think the course is great, I really wanted a way to learn LINQ more in depth and this course certainly fit the bill. Just a little feedback, and maybe this is clear to others but for those who it is not clear to, in chapter 6.4 The Select Clause, the instructor goes through the process of adding a library to LINQ Pad and never noted that after cloning the repo to your local machine, the .gitignore file purges the .dll files so in order for you to have them available in your folder to use in LINQ Pad you have to open the Visual studio solution and build it to repopulate the bin files on your local machine.
