Indicates whether a compatibility check has already been performed.
true, if the compatibility check has already been performed; otherwise, false.
The XafApplication.CustomCheckCompatibility event is raised many times - when logging on to the application, as well as when creating each Object Space. If the compatibility check is being performed for the first time, the IsCompatibilityChecked property returns false. Use this property, to perform database-intensive checking on the first compatibility check only.
