I'm porting a project from MVC into a Blazor MAUI Hybrid app with the intent to share common components and data. I have a Razor Class Library which does this, but was wondering if I should also put my SQL Server data access in here as well or keep that in the Blazor web project?

I would assume a Maui app would call a webapi to do database access (unless it's a local SqlLite database). But even in this case I expect a separate project for the database layer.
Hello,
For MAUI blazor applications, the best practices for the application database are no different from MAUI. Therefore, it is recommended that you refer to the following official documentation.
Best Regards,
Alec Liu.

The poster did say 'SQL Server' not 'SQLite' as in the link you posted. Why does MS support staff have such issues with understanding how developers build commercial systems with proper back end databases in the real world??

In most Blazor MAUI Hybrid architectures, it’s usually better to keep the data access layer separated from the UI projects and place it in a shared class library rather than directly inside the Blazor web project. That way both the MAUI Hybrid app and the web application can reuse the same business logic, repository/services, DTOs, and validation rules without duplication.
A common approach is:
Razor Class Library → shared UI/components
Separate Class Library → data access + business/services layer
Web/MAUI projects → presentation and platform-specific concerns only
The main thing to watch out for is direct SQL Server connectivity from the MAUI client side. For production apps, it’s generally safer to expose data through APIs instead of allowing the client application to connect directly to SQL Server.
