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:
Any ideas?
Possible reason: Check if there is "ReSharper" tab in the "Tools | Options" dialog, and ReSharper is not suspended. If there's no such dialog or it shows an error, continue to the next Part II of this guide (below). If ReSharper is shown as 'Suspended' in this dialog, use the "Resume" button.
In the Visual Studio menu, choose ReSharper | Options. In the Options dialog that appears, select a node in the left pane and configure settings in the right pane.
ReSharper fully supports JavaScript up to ECMAScript 2016, including experimental features such as async/await, exponentiation operator and rest/spread in object literals/destructuring. jQuery and JSX syntax are supported as well.
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.
Since the problem occurs in more than one version including latest as of writing, you also have the option to switch off TypeScript support in ReSharper. After all, if a feature is broken, why use it?
How to switch it off according to their web site:
If necessary, you can disable/enable ReSharper features in TypeScript files by clearing the corresponding check box on the Environment | Products & Feature page of ReSharper options.

After this change you may have to restart Visual Studio for the new settings to take effect.
