how to use unity3d webgl content in a asp.net mvc view?

I asked this question in stackoverflow but no answers so I think it would fit here better.

I have a unity webgl project and an asp.net mvc project.

I need to show the webgl content in a view.

The first thing that came to my mind was to simply copy the content of the index.html that unity gave me and paste it in a .cshtml file and change the addresses. But when I do this the incorrect header error pops up.

Am I doing some thing wrong or everything wrong. should I change my method entirely?

I also added these file extensions to the web.config

<staticContent>
  <!-- Unity 5.x -->
  <remove fileExtension=".mem" />
  <mimeMap fileExtension=".mem" mimeType="application/octet-stream" />
  <remove fileExtension=".data" />
  <mimeMap fileExtension=".data" mimeType="application/octet-stream" />
  <remove fileExtension=".memgz" />
  <mimeMap fileExtension=".memgz" mimeType="application/octet-stream" />
  <remove fileExtension=".datagz" />
  <mimeMap fileExtension=".datagz" mimeType="application/octet-stream" />
  <remove fileExtension=".unity3dgz" />
  <mimeMap fileExtension=".unity3dgz" mimeType="application/octet-stream" />
  <remove fileExtension=".jsgz" />
  <mimeMap fileExtension=".jsgz" mimeType="application/x-javascript; charset=UTF-8" />
</staticContent>
