Opt-in break to revert from different 4.5 SQL generation to simpler 4.0 SQL generation
Scope
Transparent
Version Introduced
4.5.2
Source Analyzer Status
Not planned
Change Description
Queries that produce JOIN statements and contain a call to a limiting operation without first using OrderBy now produce simpler SQL. After upgrading to .NET Framework 4.5, these queries produced more complicated SQL than previous versions.
- Quirked
- Optional
- Build-time break
Recommended Action
This feature is disabled by default. If Entity Framework generates extra JOIN statements that cause performance degradation, you can enable this feature by adding the following entry to the <appSettings> section of the application configuration (app.config) file:
<add key="EntityFramework_SimplifyLimitOperations" value="true" />
