  3. Page
  4. Module
  5. View
  6. User

With the ICmsContext object you can get general information about the current platform.

On the new RazorTyped it's on MyContext.Platform.

  2. .Type Current platform type is: Dnn

<ol>
  <li>
    <code>.Name</code> Current platform name is: 
    <strong>@MyContext.Platform.Name</strong>
  </li>

    <code>.Type</code> Current platform type is: 
    <strong>@MyContext.Platform.Type</strong>

With this object you can get general information about the culture.

On the new RazorTyped it's on MyContext.Culture.
