Angular Material 2 SSR doesn't work

[Jacooscript]

I have created asp.net core Angular template project in Visual studio 2017 (15.5.6). I added and configured Angular Material 2.

But when a page loads, I see a common html button. But after loading all js files, styles are applied to the button.

1. Page is loading:
   
2. Page is loaded:
   

Also I have created GIF.
I import material module in "app.shared.module.ts".

It sounds like there are additional config steps needed for Angular Material. Since that's a third-party package, I don't know what those steps are, so you'd need to check Angular Material docs for details.

However to make this easier, you might want to consider using our newer Angular CLI-based template. This means you have a completely standard Angular project, so whatever setup steps are most commonly used for third-party packages will be sure to work just the same for your project. For installation info, please see: https://docs.microsoft.com/en-us/aspnet/core/spa/angular?tabs=visual-studio

This should fix the issue: angular/components#9771

[bastienlemaitre]

It change nothing..

[chrisvfabio]

@bastienlemaitre angular/components#9771 is tagged as "release: major" so it's only available in v6+

I'm using @angular/material@5.1.0 for my Angular 5 apps.
