ReSharper TypeScript seems to be not working at all in my VS 2015 installation. Despite of the correctly placed TypeScript definitions ReSharper does not recognize the defined types, gives zillion red underlines, and of course intellisense does not work on the variables.
The error message is for example:
Could not find symbol 'JQuery'
Some more diagnostics:
If you see this kind of behaviour - lots of red, but clean compile, especially after an upgrade - you should try to clean the caches. Go to ReSharper → Options → General → Clean caches, then restart Visual Studio.
I have found that sometimes, the Visual Studio Project file is corrupted, containing multiple references to
.ts files. This can cause a different, but related error, where ReSharper thinks there are multiple declarations of a symbol.
To resolve, if you are using version control, it is simple.
As I mentioned, this doesn't solve the original problem, but can help in situations where ReSharper reports duplicate symbols.
