I have created a Blazor WASM project. It is using authentication and to do so it navigates to it's own server side pages in the area Identity. I have tried to scaffold these pages in order to change the title on the navbar but I cannot figure this out.
It currently shows the project name (i.e. BlazorApp.Server)
You have to scaffold an Identity page to get access to _Layout.cshtml. I usually scaffold the Register and Manage/Index pages.
You will find the branding your after in there.
As a side note I change the style sheet it points to to site.css in the wwwroot\css folder
<link rel="stylesheet" href="~/Identity/css/site.css" />
to
<link rel="stylesheet" href="~/css/site.css" />
