CRUD Operations Using Blazor, .Net 6.0, Entity Framework Core

Hi, new to Blazor with the Entitify framework, difficulty with appsettings.json connection string for Default Connection. Using locally hosted sql server 2014 test db.

 

multiple tries, current error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
