### Available Workarounds

Using a concrete `T[]` array instead of `IEnumerable<T>` for the configuration property works around this issue.

## macOS PKG installers missing executable bit on `createdump`

SDK and runtime installers for macOS install a `createdump` binary that lacks the executable bit. This means that scenarios that request a dump (test hang collector, `dotnet-dump collect`, collecting dumps on crash through environment variable, etc.) will fail with an error indicating that `createdump` cannot be executed.

### Available Workaround for createdump

- Add the executable bit to `shared/Microsoft.NETCore.App/10.0.0/createdump` manually using `chmod +x`
- Use another runtime hosting mechanism (self-contained app, use a tarball installation of the runtime/SDK)
