@Dreamescaper I found you fix an issue with 16.6 P3, how can I find the latest vsix file?

[Dreamescaper]

Yeah, I fixed this issue, but haven't published to marketplace. Could you test this and let me know whether everything's fine? https://ci.appveyor.com/api/buildjobs/j02c2q4m7gx4yrty/artifacts/IntelliSenseExtender%2Fbin%2FRelease%2Fnet472%2FIntelliSenseExtender.vsix

[netcore-jroger]

Ok 😃

[netcore-jroger]

@Dreamescaper Great, it work fine.

[netcore-jroger]

@Dreamescaper But he does not seem to list all available classes. such as System.IO

[netcore-jroger]

Strange, just tried it again, it's ok again.

[netcore-jroger]

I think it should be that the index has not been completed.

[Dreamescaper]

Yes. I removed support for unimported types and extension methods, since this functionality is available in VS itself now. Let me know if there's any issues with that approach.

And native completion works exactly like that - if index is not populated, it shows completion dialog without unimported types in order not to block typing.

[netcore-jroger]

Okay, if there are any questions, I will ask you at the first time.
