...and it's not working. :(

I create ASP.NET Core app from angular template. I actualy followed these directions from these official ssr docs

1. Setting up ASPNETCORE_Environment variable
2. Run dotnet new angular
3. Modify Startup.cs and add UseSpaPrerendering
4. Add settings to .angular-cli.json
5. Add tsconfig.server.json
6. Add app.server.module.ts
7. Add main.server.ts
8. Modify csproj BuildServerSideRenderer option
9. Run npm i in ClientApp directory

In Development it's work fine. But after production build it work's like in development, ssr not working. Angular continues to run on client.

My steps to build:

1. Run dotnet build -c Release -o out

2. Angular builds without errors (after build in out dir, creates 2 angular builds - dist and dist-server (dist-server size is 32Kb)

3. Run dotnet ssr.dll

These basic steps for SSR. But I modify main.ts and main.server.ts files, add these to extraProviders for main.ts

{ provide: 'OS', useValue: 'Client' }

for main.server.ts

{ provide: 'OS', useValue: 'Server' }

and modify home component import { Component, Inject } from '@angular/core';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
})
export class HomeComponent {

  os: string = null;

  constructor(@Inject('OS') public osinject: string) {
    console.log(osinject);
    this.os = osinject;
  }
}

Actualy after build and run my project, i should have seen 'Hello Server', but i see 'Hello Client'.

I tried create 2 times from scratch, tried run in docker container, tried run other projects with ssr (find in github). But it all not working for me

> dotnet --version
2.1.403

> node --version
v8.11.3

Whats went wrong guys?
