UseWebAssemblyDebugging and UseBlazorFrameworkFiles Deprecated ?

[solidcloudio]

I upgraded from 3.2.0-rc1.20223.4 to 3.2.0, I can't compile my app with -:

Severity Code Description Project File Line Suppression State
Error CS1061 'IApplicationBuilder' does not contain a definition for 'UseWebAssemblyDebugging' and no accessible extension method 'UseWebAssemblyDebugging' accepting a first argument of type 'IApplicationBuilder' could be found (are you missing a using directive or an assembly reference?) \JD.Blazor.Server\Startup.cs 412 Active

'Are these deprecated in 3.2.0? Is there a replacement ?
