IDbContextFactory<TContext> IDbContextFactory<TContext> IDbContextFactory<TContext> Interface


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 model rendering, DDL generation etc. To enable design-time instantiation for derived DbContext types that do not have a public, default constructor, implement this interface. Design-time services will auto-discover implementations of this interface that are in the same assembly as the derived DbContext type.
