NullReferenceException in KeyTipService.OnAdornerChainTerminated

[znakeeye]

Got this exception, probably when a tooltip was about to be displayed.

[System.NullReferenceException]:Object reference not set to an instance of an object.

Thanks. When are you planning a new alpha nuget build?

[batzen]

Didn't notice your comment. Will try to release a new alpha this week.

[znakeeye]

Was there a new alpha? I don't see it on nuget.org

[batzen]

There is one from 2 months ago. Will push a new one today as i updated the supported .net core version and fixed a potential endless loop in the tabscontainer.

[batzen]

Won't be able to publish today. Will try tomorrow.

[batzen]

Just published a new preview.
