Releases the resources used by the object context.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
This method closes the connection if it was opened by the Entity Framework. 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. The Dispose method does not close any explicitly opened connections.
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).
The method calls the virtual (Overridable in Visual Basic) Dispose(Boolean) method.
