getset

Gets or sets the thread pool used by the application.

If this value is set all Client Sessions or Server Instances created with this ApplicationInstanceBase will use this thread pool. If this value is left null then each Client Session or Server Instance will create its own ThreadPool. Note that operations using .NET framework asynchronous I/O capabilities will still use .NET framework ThreadPool even if this property is set. If this property is set the ThreadPool settings in the ApplicationConfiguration are ignored.

This is an example for creating the ThreadPool:

var application = new ApplicationInstanceBase()
{
    ThreadPool = new ApplicationThreadPool(10, 10000)
};

ICertificateStore UnifiedAutomation.UaBase.ApplicationInstanceBase.TrustedStore

getset

Gets or sets the trusted store.

The trusted store.

Event Documentation

EventHandler UnifiedAutomation.UaBase.ApplicationInstanceBase.ConfigurationChanged

Occurs if the configuration has changed and needs to be persisted.

This event can be raised from a background thread and BeginInvoke may need to be called if being handled by a UI.

CreateCertificateEventHandler UnifiedAutomation.UaBase.ApplicationInstanceBase.MissingApplicationCertificate

Occurs when the application certificate is missing.

This event is raised from the thread used to call Start.

UntrustedCertificateEventHandler UnifiedAutomation.UaBase.ApplicationInstanceBase.UntrustedCertificate

Occurs when an untrusted certificate is encountered.

This event can be raised from a background thread and Invoke may need to be called if being handled by a UI. This event has return parameters so BeginInvoke cannot be used. Displaying a modal dialog in the callback will not work if the UI thread is blocked on a another operation. This problem can be avoided by using asynchronous method calls when available.
