Razor Class Library is not routed properly when referenced from a WebForms project

[TPIvan]

When I create a Razor Class Library (Visual Studio 2017 + Core 2.1 Template) and reference it from an ASP.NET Core Web Application Project the Page1 created by the template is available on the address /MyFeature/Page1 . When I do the same with an ASP.NET Web Application (.NET Framework) the page is not available on the address (HTTP 404).

@TPIvan are you attempting to reference the class library from a Mvc 5 \ WebForms project? That wouldn't work. Razor Class Library requires ASP.NET Core to run.

@pranavkm
Yes this is exactly what I am doing. It seems to be possible to work with classes defined in the Razor Pages project, but not the pages.
The ability to work with Rasor Page library would easify a step by step transition from Net/Webforms to core. So the only way of connection both technologies is to have two separate processes (virtual directories)?

Yes, that would likely be the model to go with. cc @davidfowl in case you have anything further to add.

That’s right. There’s no way to host one in the other. It needs to be run side by side in different processes
