Is LINQ to SQL Classes and LINQ to sql Objects are the same thing? I'm using Visual Studio 2017 Community version and their is no LINQ to sql Classes option and instead of that it has LINQ to sql Objects.
My teacher used LINQ to sql classes and he added LINQ to sql classes their is video link the video is not in English.
After that he is dragging table to the .dbml file, but when Im trying to do the same.It isn't giving me the drag and drop facility, I think it is because I'm using Community version and I added LINQ to sql Objects file.

This is the window comes up when my teacher adds LINQ to sql Classes file.
This is the window comes up when I add LINQ to sql Objects file and it doesn't allows dragging table over it.
