Max allowed files:

Upload up to @maxAllowedFiles of up to @maxFileSize bytes:

@foreach (var file in loadedFiles)

}
@code {
private List loadedFiles = new();

private int maxAllowedFiles = 3;
private bool isLoading;

private async Task LoadFiles(InputFileChangeEventArgs e)
{
    isLoading = true;
    loadedFiles.Clear();

    foreach (var file in e.GetMultipleFiles(maxAllowedFiles))
    {
        try
        {
            loadedFiles.Add(file);

            var trustedFileNameForFileStorage = Path.GetRandomFileName();
            var path = @"D:\" + file.Name;

            await using FileStream fs = new(path, FileMode.Create);
            await file.OpenReadStream(maxFileSize).CopyToAsync(fs);
        }
        catch (Exception ex)
        {
            Console.WriteLine("File: {Filename} Error: {Error}",

set DisableImplicitFromServicesParameters to true.

builder.Services
    .AddServerSideBlazor()
    .AddHubOptions(opt =>
    {
        opt.DisableImplicitFromServicesParameters = true;
    });
