If I go to visual studio and type in MyEnumerable. , I will see a list of all the methods that can be executed from this object. This list also shows extension methods, which is great, but is there a way (keboard shortcut?) To narrow this list down to not include extension methods?
MyEnumerable.
Other than removing using System.Linq from the top of the file, no.
using System.Linq
However, you can see the type in Object Explorer that will not show extension methods.
I don't know if you can, but extension methods have a down arrow between the icon and the name, so you can at least distinguish them from instance methods.
