I create a project Blazor (ASP.NET Core hosted) and inject IUriHelper in index.cshtml but is not accessible.
I try
@page "/"
@inject Microsoft.AspNetCore.Blazor.Services.IUriHelper UriHelper
and
@page "/"
@inject IUriHelper UriHelper
                        Are you getting a compiler error? Or is it null?

```
is a new application with only the line @inject IUriHelper UriHelper
The namespace has changed:
@inject Microsoft.AspNetCore.Components.Services.IUriHelper UriHelper
                    it's works!
Has it changed again again? :D
Yes — the namespace no longer ends with .Services.
Try the interface: Microsoft.AspNetCore.Components.IUriHelper
Has it changed again again again? 😕
Yes, it’s called NavigationManager now. https://devblogs.microsoft.com/aspnet/asp-net-core-and-blazor-updates-in-net-core-3-0-preview-9/
