VerifyAccess() public method

Verifies that the current thread is the documents owner thread. Throws an InvalidOperationException if the wrong thread accesses the TextDocument.

The TextDocument class is not thread-safe. A document instance expects to have a single owner thread and will throw an InvalidOperationException when accessed from another thread. It is possible to change the owner thread using the SetOwnerThread method.
