Exception at Visual Studio startup ("may be caused by an extension") #123

Closed cdwfs closed 5 years ago

cdwfs commented 6 years ago

For months, I've been getting an exception dialog popping up shortly after launching Visual Studio (2015 or 2017):

An exception has been encountered. This may be caused by an extension.

You can get more information by examining the file 'C:\Users\[MyNameHere]\AppData\Roaming\Microsoft\VisualStudio\15.0_dd233731\ActivityLog.xml'.

I finally decided to investigate, and the only errors listed in the ActivityLog.xml file seemed to involve ShaderTools.CodeAnalysis:

I tried disabling the HLSL Tools extension, and the exception dialog did not appear after the next launch. But that's clearly not an ideal workaround :)

I'm happy to provide more details if necessary; not sure what else would be relevant. Thanks!

Thanks for logging this! I'm closing it in favour of #124, which looks like the same issue.
