Thank you for taking the time to provide your suggestion. We will do some preliminary checks to make sure we can proceed further. You will hear from us in about a week on our next steps.

This feature is already present. What do you mean? It is even present without the clever code suggestions as default upon Enter key press (or similar) - I use it all the time.

@jinujoseph Hi, any chance this can be added for the next major VS? It'd really be a huge time saver for most C# (and VB.NET etc.) devs out there.

CyrusNajmabadi commented 1 year ago

@TahirAhmadov we'd likely take contribution if you were interested. That said, collection literals will likely make this moot.

TahirAhmadov commented 1 year ago

@CyrusNajmabadi Good point about collection literals. Still, I envision an all-encompassing solution, where when doing new after an interface, possible implementers are suggested. I could potentially look into it, which repo would it be?

CyrusNajmabadi commented 1 year ago

It's this repo :-)

TahirAhmadov commented 1 year ago

@CyrusNajmabadi Yes I know that :) I meant, can you provide some pointers which folder it's in? I looked around https://github.com/dotnet/roslyn/blob/main/src/EditorFeatures/Core/IntelliSense/ and can't find it. Mind you, this is the first time I'm looking :)

This would likely be: https://github.com/dotnet/roslyn/blob/main/src/Features/Core/Portable/Completion/Providers/AbstractObjectCreationCompletionProvider.cs
