DbContextOptions Class

Definition

The options to be used by a DbContext. You normally override OnConfiguring(DbContextOptionsBuilder) or use a DbContextOptionsBuilder to create instances of this class and it is not designed to be directly constructed in your application code.

Constructors

DbContextOptions()

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

DbContextOptions(ImmutableSortedDictionary<Type,ValueTuple<IDbContextOptionsExtension,Int32>>)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

DbContextOptions(IReadOnlyDictionary<Type,IDbContextOptionsExtension>)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Freeze()

Specifies that no further configuration of this options object should occur.

GetExtension<TExtension>()

Gets the extension of the specified type. Throws if no extension of the specified type is configured.
