Angular2 and TypeScript error "Property METHOD_NAME does not exist on type 'typeof CLASS_NAME'

I need some help. I'm playing with basics of Angular2 and TypeScript as a part of my switch from A1 to A2 so something here might be obvious for you.

I have a this situation:

  1. Webpack in use.
  2. AppConfigConst holds some static, app wide configuration data.
  3. AppConfigurationInjectable takes AppConfigConst and exposes simple API to access configuration data.
  4. SelectedLanguageInjectable want's to use method from AppConfigConst and here I get this:

ERROR in [default] C:_DEV\XXX\src\app\shared\selected-language\selected-language.injectable.ts:9:46 Property 'getSupportedUiLanguages' does not exist on type 'typeof AppConfigurationInjectable'.

You have a mistake in your constructor. It should be:

constructor(private appConfiguration: AppConfigurationInjectable){

change = with :

: is for defining types in typescript = is for setting a value as you know.
