Cancel solution loading programmatically

Hello,

I'm trying to cancel a solution loading process within the IVsSolutionLoadEvents.OnBeforeOpenSolution method.

Any ideas howto accomplish it?

Returning E_FAIL or throwing exceptions does not impact the loading at all. I also tried to close the root solution element with a IVsSolution.CloseSolutionElement but it didn't work either.

Best regards,

Dimitri
