EF Core relies on a DbContext as the means to configure database access and act as a unit of work. NET Core apps that registers the context as a scoped service by default. In Blazor Server apps, scoped service registrations can be problematic because the instance is shared across components within the user's circuit. DbContext isn't thread safe and isn't designed for concurrent use.
The existing lifetimes are inappropriate for these reasons:. The following recommendations are designed to provide a consistent approach to using EF Core in Blazor Server apps. By default, consider using one context per operation. The context is designed for fast, low overhead instantiation:. For longer-lived operations that take advantage of EF Core's change tracking or concurrency control , scope the context to the lifetime of the component. The fastest way to create a new DbContext instance is by using new to create a new instance.
However, there are several scenarios that may require resolving additional dependencies. For example, you may wish to use DbContextOptions to configure the context. The recommended solution to create a new DbContext with dependencies is to use a factory. EF Core 5. The following example configures SQLite and enables data logging.
The code uses an extension method AddDbContextFactory to configure the database factory for DI and provide default options:. The factory is injected into components and used to create new instances. Wrapper is a component reference to the GridWrapper component. New DbContext instances can be created with a factory that allows you to configure the connection string per DbContext , such as when you use ASP. NET Core's Identity model. For more information, see Multi-tenancy EF Core documentation.
You may wish to create a DbContext that exists for the lifetime of a component. This allows you to use it as a unit of work and take advantage of built-in features, such as change tracking and concurrency resolution. You can use the factory to create a context and track it for the lifetime of the component. Finally, OnInitializedAsync is overridden to create a new context. In the sample app, OnInitializedAsync loads the contact in the same method:.
EnableSensitiveDataLogging includes application data in exception messages and framework logging. The logged data can include the values assigned to properties of entity instances and parameter values for commands sent to the database. Logging data with EnableSensitiveDataLogging is a security risk , as it may expose passwords and other personally identifiable information PII when it logs SQL statements executed against the database.
We recommend only enabling EnableSensitiveDataLogging for development and testing:. In Blazor Server apps, this can be problematic because the instance is shared across components within the user's circuit.
