Remarks

Apply this attribute to your root plugin class (which implements IFrontPlugin), if plugin will be installed to all iikoFronts, but several plugin instances shouldn't process same data and notifications.
For example, this can be useful for monitoring and publishing order changes to external server. Single plugin instance is enough for such tasks and multiple instances may be unwanted. Multiple plugin instances on each iikoFront will see same data due to synchronization between iikoFronts, so parallel repeated processing will lead to duplicated server calls.

Examples

Copy

[SingleInstancePlugin]
public sealed class MyPlugin : MarshalByRefObject, IFrontPlugin
{ ... }
