However, Azure App Service's own .NET Core runtime will not be updated immediately, and we would usually wait a few weeks before Microsoft rolls out the update to Azure. For applications with high security requirements, it is urgent to complete the update before …

My ASP.NET Core Route Debugger Middleware

Background In the ancient days of the .NET Framework, there was a RouteDebugger that outputs routing information for the current page in an MVC or web API app, or sees all the routing information registered in the app. The latest version of its NuGet package is 2.1.5, updated in 2016, from an article by Phil Haack 12 years ago https://haacked.com/archive/2008/03/13/url-routing-debugger.aspx …
