Blazor web app. Error "_framework/app.shared.pdb 404 (not found)" [closed]

I have a BlazorWebApp, SharedLibray and Api in one solution. WebApp and Api referenced to SharedLibrary.When I open any component in WebApp which use SharedLibrary classes. In Chrome debugger appears an error "https://localhost:5000/_framework/SharedLibrary.pdb 404 (not found) and other errors about not found SharedLibrary.

I can't understand, what is the problem. How to solve it.

I've tried to recreate SharedLibrary, delete bin and obj folders in projects and rebuilt them.
