Research direction

Start with the reported LINQ expression and the NavigationExpandingExpressionVisitor failure. Determine whether the client-server Join is an unsupported limitation or an unexpected error, then identify the exception behavior that should be improved. The issue provides no named files, tests, reproduction steps, or completion criteria.

Description

area-query customer-reported

Processing of the LINQ expression 'DbSet
.Join(
outer: __p_0,
inner: domainUser => domainUser.DomainAccessID,
outerKeySelector: domain => domain.ID,
innerKeySelector: (domainUser, domain) => new {
domainUser = domainUser,
domain = domain
})' by 'NavigationExpandingExpressionVisitor' failed. This may indicate either a bug or a limitation in EF Core. See https://go.microsoft.com/fwlink/?linkid=2101433 for more detailed information.
