Releases the resources used by the object context.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
This method closes the connection. After Dispose is called, operations that require an open connection, such as executing a query or calling theToTraceString method, will cause an exception. Operations that do not require an open connection, such as composing a query or attaching objects, will not cause an exception.
Limiting the scope of an ObjectContext within a using block (Using in Visual Basic) ensures that resources are correctly disposed. For more information, see Managing Resources in Object Services (Entity Framework).
