Description
This change introduces a deprecation warning (ASPDEPR007) that is displayed during compilation when the
IncludeOpenAPIAnalyzersproperty is set totruein Web SDK projects. The warning informs developers that the property and its associated MVC API analyzers are deprecated and will be removed in a future release.Fixes dotnet/aspnetcore#62689
Customer Impact

IncludeOpenAPIAnalyzersproperty, allowing them to plan for migration away from this deprecated functionality.Regression?
Risk
The code change itself is localized to Web SDK projects that set the
IncludeOpenAPIAnalyzers. This change does intentionally introduce a warning to appear in existing builds whereIncludeOpenAPIAnalyzersis currently set totruewhich can cause breaks in scenarios where users have enabled warn as errors.Verification
