[severity:It's more difficult to complete my work]
When adding the package Microsoft.AspNetCore.SignalR.Client to a Blazor server webassembly project that uses the target framework .NET 8.0 the project will load and appear but functionality ceases to work.

Even if you create a brand new project, add the SignalR.Client assembly,... since the project defaults to .NET6.0 it will work... when you switch to .NET 8.0, it will not.

This issue was introduced in the latest Microsoft.AspNetCore.SignalR.Client version 9. The previous version 8.0.11 seems to be ok.
