当我尝试更新我的Model.DesignedDiffs.xafml时，我得到了下面的错误日志。在阅读this post about the exception之后，我想知道是否我有一些Map函数定义不正确
例如，我的代码使用

public static List<T> SqlQueryOfT<T>(string query, string connectionString, Func<DbDataReader, T> map, params SqlParameter[] parameters)
{
    var entities = new List<T>();
    using var cn = new Microsoft.Data.SqlClient.SqlConnection(connectionString);
    using var command = new Microsoft.Data.SqlClient.SqlCommand();
    command.Connection = cn;
    command.CommandText = query;
    command.CommandType = CommandType.Text;
    foreach (var param in parameters)
        command.Parameters.Add(param);
    cn.Open();
    using var result = command.ExecuteReader();
    if (result.HasRows)
    {
        while (result.Read())
        {
            var r = map(result);
            entities.Add(r);
        }
    }
    cn.Close();
    return entities;
}

字符串
这个错误可能是因为我用一个不正确的Map调用这个函数吗？我经常调用这种函数，所以我想知道如何识别哪个Map是问题所在。
我确实安装了Develop. App.Design.NetCorePackage.2022扩展，尽管帮助中没有提到.2022

Model.DesignedDiffs.log包含：

我无法在新的XAF 23.1.6 Winforms EFCore项目中重现这个问题。
目前在我的开发项目中，我可以通过在业务类上不使用外观属性来设置字体样式来解决这个问题。
在我的代码中，当我更新模型时，以下内容将导致错误。

[DomainComponent]
[Appearance("IsPromisedApp", Criteria = "IsValid", FontStyle = System.Drawing.FontStyle.Regular)]

public class ApplicationUser : PermissionPolicyUser, IObjectSpaceLink, ISecurityUserWithLoginInfo
{
    public ApplicationUser() : base() { UserLogins = new ObservableCollection<ApplicationUserLoginInfo>(); }
    [Browsable(false)]
    [DevExpress.ExpressApp.DC.Aggregated]
    public virtual ObservableCollection<ApplicationUserLoginInfo> UserLogins { get; set; }

    public virtual bool IsValid { get; set; }
    System.Collections.Generic.IEnumerable<ISecurityUserLoginInfo> IOAuthSecurityUser.UserLogins => UserLogins.OfType<ISecurityUserLoginInfo>();

    ISecurityUserLoginInfo ISecurityUserWithLoginInfo.CreateUserLoginInfo(
        string loginProviderName,
        string providerUserKey)
    {
        ApplicationUserLoginInfo result = ((IObjectSpaceLink)this).ObjectSpace
            .CreateObject<ApplicationUserLoginInfo>();
        result.LoginProviderName = loginProviderName;
        result.ProviderUserKey = providerUserKey;
        result.User = this;
        return result;
    }
}

如果我从外观中省略字体样式，或者将外观属性移动到属性上，那么我可以更新模型而不会出错。
