EF no longer throws for QueryViews with specific characteristics

Scope

Edge

Version Introduced

4.5.2

Source Analyzer Status

Not planned

Change Description

Entity Framework no longer throws a xref:System.StackOverflowException?displayProperty=name exception when an app executes a query that involves a QueryView with a 0..1 navigation property that attempts to include the related entities as part of the query. For example, by calling .Include(e => e.RelatedNavProp).

• Quirked
• Build-time break

Recommended Action

This change only affects code that uses QueryViews with 1-0..1 relationships when running queries that call .Include. It improves reliability and should be transparent to almost all apps. However, if it causes unexpected behavior, you can disable it by adding the following entry to the <appSettings> section of the app's configuration file:

<add key="EntityFramework_SimplifyUserSpecifiedViews" value="false" />

Affected APIs

• Not detectable via API analysis
