PowerPoint Interop ConvertToAfterEffect Won't Compile in NCrunch 1.41.0.50b

I have the following in my code:

var effect = slide.TimeLine.MainSequence.AddEffect(shape, PPT.MsoAnimEffect.msoAnimEffectAppear, trigger: PPT.MsoAnimTriggerType.msoAnimTriggerAfterPrevious);      
slide.TimeLine.MainSequence.ConvertToAfterEffect(effect, PPT.MsoAnimAfterEffect.msoAnimAfterEffectHide);

Code compiles fine. Runs fine. Runs fine in MSTest.

NCrunch won't compile it giving the following excuse:

The following workaround allows NCrunch to compile:

var effect = slide.TimeLine.MainSequence.AddEffect(shape, PPT.MsoAnimEffect.msoAnimEffectAppear, trigger: PPT.MsoAnimTriggerType.msoAnimTriggerAfterPrevious);      
dynamic seq = slide.TimeLine.MainSequence;
seq.ConvertToAfterEffect(effect, PPT.MsoAnimAfterEffect.msoAnimAfterEffectHide);

Is this by design, am I doing something wrong, or is it an NCrunch bug?

Thanks,

Tony

Hi Tony -

Thanks for reporting this issue. It looks as though the syntax of this particular method call is creating a rare IL arrangement that NCrunch isn't able to process. I'll note it down for a future fix.


Thanks!
