C# - Autocompletion suggestion has immediate errors

[philipmat]

Describe the bug

in "csharp - C# Script" the auto-completions suggestions are causing immediate errors.
For example, in the screenshots/code below, the variables are of type IPagedList<T> : IList<T>.

Auto-completion suggests Select<> as a method.

Using that, completing the expression, and filling in the type yields errors:

'IPagedList' does not contain a definition for 'Select' and no accessible extension method 'Select' accepting a first argument of type 'IPagedList' could be found (are you missing a using directive or an assembly reference?)

Except it should because System.Linq is part of the usings, and the simpler/type-inferred Select() method works just fine.

Or rather: why is Autocomplete suggesting something that wouldn't work?
