我正在开发沙盒解决方案 SharePoint 2010（SharePoint Online 项目）。

我得到的错误是

Error   19  Error occurred in deployment step 'Add Solution': This solution contains invalid markup or elements that cannot be deployed as part of a sandboxed solution. Solution manifest for solution 'c353c02e-f7b0-4c58-b7c6-066adf1d7e0c' failed validation, file manifest.xml, line 3, character 4: The element 'Solution' in namespace 'http://schemas.microsoft.com/sharepoint/' has invalid child element 'CodeAccessSecurity' in namespace 'http://schemas.microsoft.com/sharepoint/'.

我在 Visual Studio 中的清单文件（Package.package）看起来像这样

如果我从“解决方案”元素中删除“CodeAccessSecurity”标签，则解决方案将从 VS 部署和激活，没有任何问题。我无法从网络激活解决方案，我试过了。

该解决方案包含一个 Web 部件，它使用 LINQ 从其他列表中获取数据 + 在列表中创建一个新的列表项。

我在“解决方案”中添加了“CodeAccessSecurity”标签，因为没有它我得到一个错误

当代码尝试创建新列表项时，我收到上述错误。

我正在使用沙盒可视化 Web 部件。

如果我从“解决方案”中删除“CodeAccessSecurity”子元素但我无法创建新的列表项，则该解决方案被激活，没有任何问题。我正在使用 LINQ to SharePoint 创建一个新的列表项

如果我不使用数据上下文来创建新的列表项，那么以下代码可以完美运行

 SPList list = objWeb.Lists.TryGetList("ListName");
                        SPListItem newListItem = list.AddItem();
                        newListItem["Department"] = new SPFieldLookupValue(int.Parse(ddlDepartment.SelectedValue), ddlDepartment.SelectedItem.Text);

                        newListItem.Update();

如果您有任何其他想法，请告诉我
