Once installed .net 9 preview, wsfsc not working!!

[ingted]

The projects are not changed (targeting .net version/websharper lib references...) but not able to build after .net 9 preview installed.

In event viewer, application log:

Application: wsfsc.exe
CoreCLR Version: 9.0.24.40507
.NET Version: 9.0.0-preview.7.24405.7
Description: The process was terminated due to an unhandled exception.
Exception Info: System.PlatformNotSupportedException: BinaryFormatter serialization and deserialization have been removed. See https://aka.ms/binaryformatter for more information.

Error during build process for a websharper project:

C:\Users\anibal\.nuget\packages\websharper.fsharp\6.1.5.317\build\WebSharper.FSharp.targets(50,5): error MSB6006: "wsfsc.exe" exited with code -532462766. [G:\coldfar_py\sharftrade7\
FAkka.Server\FAkka.Server.fsproj]

My project is targeting .net 7 and it used to be able to build. (see. FAkka.Server)

global.json

  "sdk": {
    "version": "7.0.400"

@ingted There should be a new version on nuget (6.1.7.476) out there to remove the usage of BinaryFormatter for WebSharper 6
