“No provider for AuthGuard!” using CanActivate in Angular 2

Question

EDIT : Obviously this is outdated, now you provide your guard at the providers array in an NgModule. Watch other answers or official documentation

Answer 1

I encountered this issue when I was following a tutorial. I tried most of the answer here but not getting any success. Then I tried the silly way like putting the AuthGuard before the other services in the provider and it works.

// app.module.ts

 .. 
 providers: [
   AuthGuard,
   UserService,
   ProjectService
  ]
