After years away from writing code in a Windows app, I want to resurrect a 1990s-era Visual Basic desktop app and 'refactor' it in C#. These sessions show me that I can enjoy doing what I did back then in a much more efficient manner. I am also hoping to find sessions that demonstrate how to call Windows functions in the various DLLs that comprise Windows today, and save even more code writing.

2:19 Concept 8:50 LINQ on T var nums = new List() { 1, 2, 3, 4, 5 }; IEnumerable queries = from num in nums where num > 3 select num; queries.ToList().ForEach(x => Console.WriteLine(x));

@jessedv5915 2 месяца назад

for the 1st part you can just write// List nums =[1, 2, 3, 4, 5]; ........................................................//IEnumerable numQuery

I've used C and C++. This LINQ is new to me. But I've also done db queries. Does it matter if from/where/select are in that order? The reason I ask is it would look like a db query if it was select/from/where.

create a project like they told in the beginning lectures inside the project folder you can see a .csproj file in it set targetframework to 8 (net8.0) (btw this needs dotnet 8 to be installed to work)
