1. Add a NUGET reference to the DXApplication4.Blazor. Server project
2. Add assembly reference to Program.cs

[assembly: HostingStartup(typeof(Xpand.Extensions.Blazor.HostingStartup))]
[assembly: HostingStartup(typeof(Xpand.XAF.Modules.Blazor.BlazorStartup))]
namespace DXApplication4.Blazor.Server;

4. Add BlazorModule reference to module.cs in the Blazor project
   RequiredModuleTypes.Add(typeof(Xpand.XAF.Modules.Blazor.BlazorModule));
5. Generate project
6. Right click on the blazor.server project and click on update model

   Unable to find file version 5.0.0.0 in the error message, but the compiled file version is 5.0.0.1

Here is he demo.

[apobekiaris]

<PackageReference Include="System.Interactive" Version="6.0.1" />
<PackageReference Include="System.Interactive.Async" Version="6.0.1" />

add it in your Blazor project and let me know if it worked

[yunits]

after adding these packages to your project rebuild your solution.
To see Model Editor again you also need restart visual studio

Thank you.
After installing specific packages, there were no more error messages. But a new issue arose, the uploadpropertyeditor was not displayed in model.xafml, and even if I specified the editor in the code, it still wouldn't work. After opening the page, it is still a regular listview.

here is the code.
`[DefaultClassOptions]
[DefaultProperty(nameof(Name))]
public class Emplyee : BaseObject
{
public Emplyee(Session session) : base(session)
{ }

string fName;

[Size(SizeAttribute.DefaultStringMappingFieldSize)]
public string Name
{
    get => fName;
    set => SetPropertyValue(nameof(Name), ref fName, value);
}

[PersistentAlias("EmployeeDatas.Count")]
[EditorAlias(nameof(DisplayTextPropertyEditor))]
public int FileCount => (int)EvaluateAlias();

[Association("Emplyee-EmployeeDatas")]
[EditorAlias("UploadFilePropertyEditor")]
public XPCollection<EmployeeFileData> EmployeeDatas
{
    get
    {
        return GetCollection<EmployeeFileData>(nameof(EmployeeDatas));
    }
}

}

//[DefaultClassOptions]
public class EmployeeFileData : FileData
{
public EmployeeFileData(Session session) : base(session)
{ }

Emplyee fEmployee;

[Association("Emplyee-EmployeeDatas")]
public Emplyee Employee
{
    get => fEmployee;
    set => SetPropertyValue(nameof(Employee), ref fEmployee, value);
}

}`

here is the screenshot,there is no uploadpropertyeditor.

here is the sample.

probably some breaking change in the Xaf code or improvment. In any case you can workaround it like

public IEnumerable<IFileData> Datas => EmployeeDatas;

also if u have the time u can create your custom editor without any implementation mark it with [PropertyEditor(typeof(IEnumerable<IFileData>),EditorAliases.UploadFile, false)], create a sample and ask in DX support center explaining to them that the time I recorded the video in the wiki it was working
