Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type DbContext. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The stored procedure name is determined by looking for the DeleteEntityStoredProcedureAttribute on the entity type. The stored procedure must have one or more parameters representing the key columns on the entity type identified with a PrimaryKeyAttribute or one or more properties with a KeyAttribute or defined by the data context. It should not return a value or a result set. All parameters are input only.

If the connection is not in an open state, it is opened temporarily while deleting the entity. If change tracking is enabled on the data context and the entity its state will be set to unattached.

Example

C#

using var dataContext = new MyDbContext();

dataContext.DeleteEntity(watchListItem);
