Caution

Use IDesignTimeDbContextFactory instead.

A factory for creating derived DbContext instances. Implement this interface to enable design-time services for context types that do not have a public default constructor. At design-time, derived DbContext instances can be created in order to enable specific design-time experiences such as Migrations. Design-time services will automatically discover implementations of this interface that are in the same assembly as the derived context.

Type Parameters

TContext

The type of the context.
