basic component layout inheritance blazor

Let's say most of my components have a header. I want to create a base component that has the header variable and make all the other components inherit from that component and set the header. So I have

BaseComponent

@inherits LayoutComponentBase;<h1>@header</h1>@Body@code {    protected string header;}

Component

@inherits BaseComponent;"internal component text"@code {  protected override void OnInitialized()    {         base.header = "Setting header for the parent"    }}

This compiles and shows up with no errors but the base header doesn't show up. It's like anything in the base doesn't get rendered. What am I doing wrong?

P.S.

I have also tried @layout BaseComponent, and even both directives at the same time.
