Attributes

Remarks

This event does not fire when a solution is first opened. OnAfterBackgroundSolutionLoadComplete fires after all background loading projects have completed and the initial opening of the solution has reached the SolutionExistsAndFullyLoaded_guid state. After this point, if a new group of projects begins loading in the background, then this event will fire. This could occur if the user causes the loading of a PLP_LoadIfNeeded project (for example, by expanding the pending project in the Solution Explorer) or if the solution load manager changes an unloaded project's load priority from PLP_ExplicitLoadOnly or PLP_LoadIfNeeded to PLP_BackgroundLoad. When a new group of projects starts loading in the background in this manner, the SolutionExistsAndFullyLoaded_guid context is deactivated again. When background loading is completed, then the OnAfterBackgroundSolutionLoadComplete event fires, and the SolutionExistsAndFullyLoaded_guid is activated again.
