Coco V3.0.0 crashes on opening non-cs-files
Closed this issue · 2 comments
I encounter regular crashes of Coco in Visual Studio 2017.
The error mainly occurs if i open files other then Cs-files (i.e. rdlc files, xml-files,....)
So here are the key data:
CoCo-Version 3.0.0
Visual Studio Version: Visual Studio 2017 Enterprise, V15.9.11
Error (logged in ActivityLog.xml):
System.AggregateException: One or more errors occurred.

@dreammaster38, Thanks for you feedback!
Fix of this issue would be included to the next 3.1.0 version of CoCo. Currently I close this issue, but you can reopen it if you will have some exceptions on the new version.
@dreammaster38, you can check a new version of extension. So let me know if you have still exceptions.
