This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases. |
| RelationalQueryContext(Func<IQueryBuffer>, IRelationalConnection, LazyRef<IStateManager>, IConcurrencyDetector, IExecutionStrategyFactory) |
This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases. |
| RelationalQueryContext(QueryContextDependencies, Func<IQueryBuffer>, IRelationalConnection, IExecutionStrategyFactory) |
This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases. |
| RelationalQueryContext(QueryContextDependencies, RelationalQueryContextDependencies) |
Creates a new RelationalQueryContext instance. This type is typically used by database providers (and other extensions). It is generally not used in application code. |

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.
