Aspnetcore documentation + runtime issues with the latest versions?

[OkayX6]

Hi!

My project targets .NET 8.0

Incomplete sample code?

I found that this documentation is not working on my project

I had to add this extra line (Cursor told me how to fix it 🤷)

Additional config needed

Also I ran into this exception

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.
      System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.Primitives, Version=9.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.
      File name: 'Microsoft.Extensions.Primitives, Version=9.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

         at <StartupCode$Fable-Remoting-AspNetCore>.$Middleware.Invoke@144.MoveNext()
         at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddlewareImpl.Invoke(HttpContext context)

I fixed it by adding a package reference

<PackageReference Include="Microsoft.Extensions.Primitives" Version="9.0.0" />

hi there @OkayX6 thanks for opening the issue! I have not used the middleware in a while and I think an update is due for the remoting packages, moving them to latest net9.0 or net8.0 cc @kerams

As for the issue with |> Remoting.withRouteBuilder routePaths is it not in the docs because it is optional: you only need to specify the route paths on the server if the client also specifies them (keeping them both in sync)
