Build fails once .NET Core SDK 3 is installed

[azeno]

Just came up here that a project referencing ImmutableObjectGraph failed to build the moment .NET Core SDK 3 was installed. Something about dotnet-codegen --info
Once I uninstalled .NET Core SDK 3 all worked fine again.

Any ideas?

Curious. I'll guess that ImmutableObjectGraph needs an update to the latest CodeGeneration.Roslyn.
Thanks for reporting.
