Lower Route Api Dotnet Core
When working with attribute routing in Web API 2 or MVC 5 it was relatively easy to get the route to the controller and the controller name out of sync. That was because the route always had to be specified as a string, so whenever you changed the name of the controller you would always have to change the string in the route attribute too.That could be easily forgotten – especially if you use refactoring tools of Visual Studio or an external refactoring plugin.This issue has been addressed in MVC6 with a tiny addition – the introduction of controller ad action tokens into attribute routing.The problemIn a typical Web API project (actually, MVC as well), you might have a controller like this. In either case, the relationship between the controller and its route, and the action and its route, were non-existant – purely relying on the fact that you maintain them by hand. (note, if you read my you might be aware of a ).
The solution in MVC6By using the new controller token in your attribute routes you can ensure that the controller name in the route, is kept in sync with the name of the controller class. In the example below, controller will always be expanded to the name of the controller regardless of any future refactorings – in this case it will be Hello. How does it work under the hood?ASP.NET MVC will use a class called AttributeRouteModel and its public static method ReplaceTokens to replace the tokens with the values from route defaults.Since the controller and action names are guaranteed to be in the route dictionary defaults, the tokens are certain to be expanded correctly. This process happens only once – at application startup, for all routes, from within the ControllerActionDescriptorBuilder class and its Build method.If you go a step earlier in the MVC setup process, the builder itself is called from within ControllerActionDescriptorProvider which is an IActionDescriptorProvider. The purpose of the provider is to provide a set of action descriptors which represent all callable HTTP endpoints of your application. The provider technically can be customized/replaced – however, this shouldn’t be done.

As from the MVC team pointed out, they actually recommend using the to customize the ActionDescriptors instead. Archives. (1). (1). (1). (1). (1).

.NET Core 3.0 Preview Known IssuesThis document lists known issues for.NET Core 3.0 Preview releases which may be encountered during usage.NET Core Preview 5.Visual style in WinForms app not showing correctly when publishing with PublishReadyToRun=trueThe ReadyToRun compiler in this preview does not copy Win32 resources from the managed assembly to the compiled output binary, which causes an issue with visual styles in WinForms apps. The workaround is to skip compilation of System.Windows.Forms.dll by adding the following to the project file.Scaffolding hangs indefinitelyWith a 3.0.100-preview5 SDK installed, and Visual Studio 16.0-preview2 or earlier, attempting to scaffold a.NET Core 3.0 project in Visual Studio will cause Visual Studio to hang indefinitely, with no indication of the problem. AddRouting( r = r. SuppressCheckForUnhandledSecurityMetadata = true);The first option would be preferred since it's not removing a check for a mis-configured application.RESOLVED Design-time errors in Visual Studio when using a component with child content from a component that lives in a different namespaceThis issue will be addressed in a future preview of Visual Studio.
