Class RazorComponent

The base class for Razor-Components in 2sxc 10+
Provides context infos like the Dnn object, helpers like Edit and much more.

To use this, create cshtml files like _person-list.cshtml in your app-folder. By default, they will be typed the old way - which continues to work for compatibility. We recommend to use this from now on. To do it, your code file must begin with an @inherits statement, like this:

@inherits ToSic.Sxc.Dnn.RazorComponent

<h1>hello from RazorComponent</h1>
