Can't debug .net core app after installing .net 7 preview 6


I am using latest VS 2022 preview version on Windows.

After I install the .net 7 preview 6 SDK, I can’t debug the app. I didn’t change any code.

If I uninstall the .net 7 preview 6 SDK, everything is back to normal.

Could you have a look? Thanks.


Which version do you have installed/use when you uninstall .NET 6 Preview 6? Also whats your CPU architecture and what version (arm64 on x86_64) of the .NET Core SDK did you install?


Hmm, yeah curious; I have Preview 3 and 4 installed, and now also installed 6, and it falls back to using /usr/local/share/dotnet/shared/Microsoft.NETCore.App/7.0.0-preview.3.22175.4/libdbgshim.dylib for me, because it seems the later previews no longer include that library :(.

Not sure of that is “as designed” or a bug with the previews; we’ll have to investigate. Unfortunately, my colleague who’s in charge of this is off on vacation this week.

Workaround for now: install/keep Preview 3 as well.

le sigh.

Thanks. I saw latest post, OK, I will install/keep Preview 3 as well.
