-// Workaround for #1066

-// The issue is that @types/react-router@4.0.12 is incompatible with @types/react@15.0.29
-// This is a problem because the ReactReduxSpa template that ships in 2.0.0-preview2 is pinned
-// to @types/react@15.0.29 but does *not* declare a direct dependency on @types/react-router,
-// which means we end up grabbing the latest @types/react-router.
-//
-// The temporary solution is for aspnet-webpack-react to add the following extra type information
-// that patches the compatibility issue. The longer-term solution will be for the templates to
-// pin versions of *every* package in the transitive closure, not just their direct dependencies.
-//
-// Note that for this workaround to work, the developer also needs 'aspnet-webpack-react' to be
-// present in the 'types' array in tsconfig.json. We automate the task of adding that in the
-// scripts/postinstall.js file in this package. Later, that action can be removed.
