Also from the issue comment

The auto import path seems to be affected by this change. E.g. previously I have a module of which the auto import path is shared but now it's shared/src/library.
The shared module is a linked module which is also one of the referenced projects, it has package.json with types set to bld/library/index.d.ts and I guess that's why the auto import path worked as shared instead of shared/bld/library.

@vilic the repro you provided has some issues.. I don't see module resolution happening..

@sheetalkamat Are you using yarn or npm? The repro is using yarn workspaces linking projects.

[sheetalkamat]

I have cloned and ran the tsc with nightly. If those aren't the steps to repro, please provide correct repro steps.

[vilicvane]

@sheetalkamat Steps after clone:

1. yarn under the project directory.
2. yarn tsc --build (Expecting error Cannot find name 'foo'.)
3. Open project with VSCode and open app/src/program/index.ts, and try auto fixes on identifier foo.

BTW just confirmed that setting disableSourceOfProjectReferenceRedirect as true brings back the old behavior.

Is there any way to get intellisence proposals across referenced projects when the "shared" project has a directory of type declarations? So multiple d.ts files instead of just index.d.ts.
