.NET Core 应用程序不支持 CodeDOM 格式的反序列化。 [XAF Winforms]

Question

我最近用 24.1.3 升级了我的 .Net Framework XAF Winforms 应用程序.Net8

如下

   public static void DoPrintReport(DevExpress.ExpressApp.View view, IReportDataV2 reportData, ReportsModuleV2 reportsModule)
   {
       //var report = ReportDataProvider.ReportsStorage.LoadReport(reportData);
       // IReportStorage reportStorage = ReportDataProvider.GetReportStorage(Application.ServiceProvider);
       // https://supportcenter.devexpress.com/ticket/details/bc4930/web-reporting-deserialization-from-the-codedom-format-has-been-disabled

       // changed to
       IReportStorage reportStorage = ReportDataProvider.GetReportStorage(null);
       var report = reportStorage.LoadReport(reportData); // gives error 

当运行时我得到

Deserialization from CodeDOM format is not supported in .NET Core applications.

报告存储在ReportDataV2表中

从此帮助我知道我需要将报告记录的内容字段转换为XML格式。

我想知道怎么做。或者是否有某种标志可以使其工作，因为我在 Winforms 中运行。

更新

研究编写框架应用程序来进行转换。 事实证明这很困难，因为最新的 xaf 向导不支持带有 .Net Framework 的实体框架

更新

我尝试重新安装 XAF 20.2.3，但 VS2022 不是受支持的 IDE

试试这个，我使用的是 v.22。*

try
 {
     xtraOpenFileDialog1.Filter = "repx files (*.repx)|*.repx";

     var dr = xtraOpenFileDialog1.ShowDialog();

     if (dr == DialogResult.OK)
     {
         XtraReport report = new XtraReport();
         report.LoadLayout(xtraOpenFileDialog1.FileName);
         report.SaveLayoutToXml(xtraOpenFileDialog1.FileName);

         MessageBox.Show($"File '{xtraOpenFileDialog1.SafeFileName}' coverted to XML format");
     }
 }
 catch (Exception ex)
 {
     MessageBox.Show($"File '{xtraOpenFileDialog1.SafeFileName}' failed to covert to XML format");
 }
