I have Visual Studio 2015 Enterprise, version 14.0.24720.00 Update 1 as well as ReSharper 10 Ultimate, version 10.0.2 installed. I have a typescript file that is using AtScript syntax to refer to the Angular2 directive module, as its annotation. However, ReSharper is stating the following error:
Symbol 'Directive' cannot be properly resolved, probably it is located in inaccessible module.
The issue is simply a bug with the latest version of ReSharper, if you Suspend ReSharper the issue simply goes away and all the source code works as expected.
This has since been addressed in the ReSharper 2016.1 version.
