title: Updating ASP.Net Core Angular template from Version 8 to 9
body: <p>The book that i read has version 9 from the beginning (ASP.NET Core 3 and Angular 9 - Third Edition) and uses also the angular template. I have the latest visual studio updates for vs 2019 installed.</p>
  
  <p>The template of a Angular project has version 8. The book I read is with version 9. So i try to update my angular version.
  <code>ng update</code> gives me </p>
  
  <pre><code>@angular/cli 8.3.14 -&gt; 9.0.3 ng update @angular/cli
  
  @angular/core 8.2.12 -&gt; 9.0.3 ng update @angular/core
  
  @nguniversal/aspnetcore-engine 8.1.1 -&gt; 8.2.6 ng update @nguniversal/aspnetcore-engine
  </code></pre>
  
  <p>I updated cli and core. But when I try to update the third package I get:</p>
  
  <pre><code>C:\Users\user\Test\ClientApp&gt;ng update @nguniversal/aspnetcore-engine
  Using package manager: 'npm'
  Collecting installed dependencies...
  Found 39 dependencies.
  Package '@nguniversal/aspnetcore-engine' is not a dependency.

  <p>I tried to run the application anyway and I get as HTML</p>
