are you getting this error in VS code? or build time? I believe it has to do with the files array in the tsconfig and not putting in a rootDir in there are well.

[philjones88]

In VS Code (insiders).

I don't get this on other projects where I used your angular-starter project so maybe it's a difference in the tsconfig files?

[Hendrixer]

right, i can confirm it has to do with the lack of "rootDir" in the tsconfig

[philjones88]

I don't know if that's right? I use the angular-starter tsconfig.json in our product and we don't get this warning? Let me test what settings from the angular-starter tsconfig.json fix it :)

[Hendrixer]

in my case it was. The real issue is when you have a file not being included by the tsconfig. This can be from rootDir, excludes, or files.

I can't replicate it tonight. VS Code has now decided that in lib.component.ts that the template property is missing even though it's right there! :(

severity: 'Error'
message: 'Component LibComponent must have a template or templateUrl'

In VSCode, Go to File => Preferences => Settings (or Control+comma) and it will open the User Settings file. Add "javascript.implicitProjectConfig.experimentalDecorators": true to the file and it should fix it. It did for me.
