Courses Plus Student 11,987 PointsWhat would the main purpose be to add LINQ queries to your program?
I imagine this would be useful by adding these queries to an application where it is attached to a submit button or search function. Other than that I don't see a point to add queries.

You're probably just seeing a specific aspect of it in this EF course, but there's another one that focuses on it directly called Querying With LINQ that you might enjoy.

Courses Plus Student 11,987 PointsAh yes that course uses the command line and csharp which isn't useful if you are new and trying to visualize the complete code. I was frustrated with that course and broke off to this one which is a lot better by actually using Visual Studio and I can attest that I learned better about LINQ in this course.
So speaking of other aspects to use LINQ, you could use a query in LINQ to return a filtered list in a function?
Steven Parker
231,275 PointsSure, that would be a typical use of LINQ.

Let's suppose you have a database table called students and it has studentID, first_name, last_name, age. You can show or return a list of items(students) in ur ASP program. Instead of typing"SELECT * FROM students" use LINQ queries.
