Threading

An instance of a CreaSign component is not safe for multithreaded operation.

You must make sure that a specific instance of a CreaSign component is not accessed from two different threads simultaneously. Exceptions to this rule are the methods of the IUnknown interface (AddRef, Release, QueryInterface). Those methods are safe for multithreaded operation.

You can access different instances of a CreaSign component from different threads simultaneously. Instances do not share state and are therefore safe for multithreaded operation.

The threading model of COM components, provided by CreaSign, is set to 'Both'. This increases the performance and avoids the creation of COM proxies.

When CreaSign creates a new instance of an XML document, it uses the free threaded version of the XML document (FreeThreadedDomDocument40), which is suitable for use in a server environment.
