部署步骤中出现错误添加解决方案

我正在使用沙盒解决方案SharePoint 2010（SharePoint Online项目）。部署步骤中出现错误添加解决方案

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/'. List of possible elements expected: 'FeatureManifests, Assemblies, ActivationDependencies' in namespace 'http://schemas.microsoft.com/sharepoint/'.

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

如果我从 “解决方案” 元素中删除 “CodeAccessSecurity” 标签那么该解决方案将在VS中部署和激活，不会有任何问题。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使用LINQ从其他列表中获取数据的Web部件+在列表中创建一个新的列表项。

我addedd的“CodeAccessSecurity”标签中的“解决方案”，因为没有它，我得到了一个错误

我得到上述错误代码时试着建立一个新的列表项。

我正在使用沙盒视觉web部分。

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，则解决方案无任何问题被激活。我使用LINQ到SharePoint以创建一个新的列表项

如果我不使用的数据上下文来创建新的列表项然后将以下代码工作完美

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，请让我知道
