Gets a value indicating whether access to the configuration attribute collection is synchronized (thread safe).
Assembly: Microsoft.Web.Administration (in Microsoft.Web.Administration.dll)
The property gets an object that you can use to synchronize access to the ConfigurationAttributeCollection object.
Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions that result from changes made by other threads. To enable the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
