EF Core 7.0 (and earlier) has the following NavigationEntry.LoadAsync(...) API:

This API was removed in EF Core 8.0 (without being obsoleted first, BTW...) and replaced by:

The signature has changed in a breaking way (an optional parameter has been added), which causes MemberMissingExceptions when referencing EF Core 8.0 in a project that has dependencies built against EF Core 7.0 (or earlier).

System.MissingMethodException : 'Method not found: 'System.Threading.Tasks.Task Microsoft.EntityFrameworkCore.ChangeTracking.NavigationEntry.LoadAsync(System.Threading.CancellationToken)'.'

Since it was requested by @roji, I attached a simple repro.

(it's very likely other APIs - like Load - have the same issue)
