I couldn’t start my executable from Visual Studio due to this issue. I could see this environment variable having an empty value using process explorer, but like others I did not set it. I had just upgraded from 17.6.4 to 17.6.5 which updated my .net 7 install from 7.0.7 to 7.0.9 when the error started.
Searching on
DOTNET_STARTUP_HOOKS
within Visual Studio’s install location, I got a hit inC:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\servicehub.config.json
. This was being set to an empty string there:Removing it from
additionalEnvironmentVariables
should also resolve the issue for others until this fix filters through as an update. I did restart the machine to ensure this new config was applied correctly.I agree - I think we should propose backporting.
