TypeScript: New class in second project is only recognized by intellisense after restart

[mahop-net]

Issue Type: Bug

• Load a folder with multiple typescript projects
• e.g.: folder structure:
  • projects
    • project1
    • project2
• e.g.: project2 references project1 via project references in tsconfig
• Add a new class in an new .ts file in project1
• Try to use this class in project2
• Intellisence does not know about this class and it is reported as error if you just type it.

Workaround:

• Restart VSCode
• After restart the new class is available via intellisense and not reported as error any more

Fix:

• This should work without a restart...

@Hopfenspirger Does this reproduce in the latest VS Code insiders build, which includes TS 3.8?

If so, can you please share a small example project that demonstrates this?

[mahop-net]

@mjbvz yes, it reproduces in latest VS Code insiders build. See the following sample and follow the steps in ./Project2/src/class2.ts to reproduce the issue.

@Hopfenspirger does it work after a full build?

[mahop-net]

What do you mean with full build?
(starting a full tsc build from the command line is working... It's only a problem for intellisense...)

When project is opened, we do not watch for changes to referenced project's files (added or removed files) which results in this. Would need some change in how we watch the referenced project's wild card directories.
