I will investigate, but the trace shows that an error is still reported by the tsserver. There is little we can do if this is the case.

[dbaeumer]

OK. The problem was that I still called realpath however the workbench and other parts didn't. After fixing this renaming back and forth works.

@chrmarti can you please verify on Mac.

[dbaeumer]

Reopening the issue. Even with the fix I can still reproduce this under Mac. TS bug to track: microsoft/TypeScript#11206

[dbaeumer]

However Windows looks good if both files are open. If only app.ts is open and bar.ts is renamed then things fail as well.

[dbaeumer]

This is getting more wired. Now I can reproduce this on Windows as well.

[dbaeumer]

Moving to October. There is nothing I can do today. More fixing requires a TS update.

[dbaeumer]

This got fixed with the latest upgrade to TS 2.0.6 were we now use one inferred project.
