Question

I have a requirement like , i need to create the Site Templates programatically. when i am trying to save the Site As Template Programatically , i am getting the below error. "Error generating solution files in temporary directory". i have given full control on c:\windows\temp directory.And I am using below Method:

oWeb.SaveAsTemplate(templateName, templateTitle, tmplDesc, true);

(or)

string solutionFileUrl = SPSolutionExporter.ExportWebToGallery(oWeb,templateName, templateTitle,tmplDesc,SPSolutionExporter.ExportMode.FullReuse,true);

facing the same issue.

i am able to save root web as Template like SPContext.Current.Web.SaveAsTemplate(templateName, templateTitle, tmplDesc, true); but i need to save sub site as Template.

Below is my ULS log dump

below code is used to save the site as Template(Root Level/subsite)

using System.Management;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
Add Reference to your solution from the below path.

Reference Path: C:\Windows\winsxs\msil_system.management.automation_31bf3856ad364e35_7.1.7601.18071_none_a682d4c5c360dacf\System.Management.Automation.dll

RunspaceInvoke oRunSpaceInvoke = new RunspaceInvoke();
                    FullWebUrl = SPContext.Current.Site.Url + "/" + objTemplate.strWebName;
                    strScriptToSaveTemp = @"Add-PSSnapin Microsoft.SharePoint.PowerShell ; Set-ExecutionPolicy -ExecutionPolicy RemoteSigned ;" +
                                    "$oWeb = Get-SPWeb " + FullWebUrl + " ; $oWeb.SaveAsTemplate('" + objTemplate.strTemplateTitle + "','" + objTemplate.strTemplateName + "','" + objTemplate.strTemplateDesc + "',1) \n";
oRunSpaceInvoke.Invoke(strScriptToSaveTemp).ToString();

Answer 2

If you have added any fields through a feature, and your field has Overwrite="FALSE", then site exporting will fail. You should only use Overwrite if you need to set it to TRUE, since the default is FALSE.

This seems to be a SharePoint bug.

You may see this attribute mentioned in your ULS logs.
