OnTopic 4.6.0 includes a few minor features, most notably improvements over routing and reporting for the ASP.NET Core TopicController. In addition, it upgrades the underlying code to C# 9.0 in order to take advantage of some new capabilities such as improved pattern matching and implicitly typed initializers.

Features

• Updated [ValidateTopic] attribute to redirect to canonical URL to ensure consistency in analytics, indexes (0edab34)
• Updated Topic.Load(RouteData) extension to return null if an invalid Key is submitted (b303f13); this results in the TopicController treating incorrect topic paths (e.g., /Web/!@~/) as 404s instead of exceptions
• Added support for enabling (IsIndexed) and configuring (IndexLabel) an optional table of contents to the ContentListTopicViewModel (e9ccb06)

Bug Fixes

• Fixed issue with where the delegate is validated in the HierarchicalTopicMappingService.GetViewModelAsnc() method (69dff49)

Improvements

• Updated code to use C# 9.0 pattern matching and implicitly typed initializers (d63f2b5)
• Updated to latest versions of internal packages, and implemented (4838da8)
• Updated to latest version of Code Analysis and fixed most issues introduced with C# 9.0 (089c96a)

Note: There are some Code Analysis false positives that remain with C# 9.0. Those are presumably fixed with the new Microsoft.CodeAnalysis.NetAnalyzers 5.0.0. There appears to be a bug in getting that to work with .NET 3.x projects, however, so it's not yet implemented. That will be revisited in a future release.
