Blazor Interactive Server with Individual Accounts lacks Bootstrap when sample pages are excluded

[mahdiyar021]

Summary
When creating a Blazor Web App in Interactive Server mode with authentication set to Individual Accounts and opting out of the sample pages, the project does not include Bootstrap. As a result, the authentication UI (login/register/manage) renders unstyled, despite the template assuming Bootstrap-based styles.

Steps to reproduce

• Create project (CLI):
  dotnet new blazor --interactivity Server --auth Individual --empty true -o BlazorAuthNoSamples
  Run the app:

cd BlazorAuthNoSamples
dotnet run

• Navigate:
• Go to the login or register pages.
• Observe:
• Authentication pages are unstyled (no Bootstrap classes rendered as expected).

Expected behavior

• Bootstrap included: The template should include Bootstrap (CSS link and, optionally, JS) when authentication is set to Individual Accounts, even if sample pages are excluded.
• Styled auth UI: Identity/auth components should render with expected Bootstrap styling out of the box.

Actual behavior

• No Bootstrap reference: The generated project omits Bootstrap when --empty true (or “Do not include sample pages”) is selected.
• Unstyled pages: Authentication-related pages render without styling.

Environment

• .NET SDK: [e.g., 8.0.x or 9.0.x]
• Template: Blazor Web App
• Interactivity: Server
• Auth: Individual
• Include sample pages: No (--empty true)
• OS: Windows 11 (build/version)
• IDE: [e.g., Visual Studio 2022 17.x]

@mahdiyar021 thanks for contacting us.

I suspect this is by design as the layout is provided for the app and you explicitly asked for no samples (which is a bad name, because it also means no styling and so on).
